Fuel tank differences between GEMS and Thor

[Keithy P38]

Hey all,

Wondering what the differences are in the two tanks (other than the obvious difference in fuel pump and sender unit)?

I'm almost certain Thor's don't have a return fuel line, but can't think of anything else.

Cheers

Mate

Off the top of my head the tanks themselves look the same, but they have different part numbers so I suspect a difference where the fuel pump goes in

Steve

[Keithy P38]

Ok thanks Steve!

I'm looking at a Brown Davis tank on gumtree, pulled out of a GEMS P38 (and Brown Davis have two part #'s for P38's too)...

I'd hate to buy it and find out I can't use it.

Cheers

[Keithy P38]

Are the senders interchangeable between gems and Thor I wonder?

I could get a gems sender and mount an external fuel filter if that's the case.

I've not seen a THOR pump assembly out of the P38 but the one out of the D2 is very similar in design. They are a complete pump, sender and surge tank that fits into the top of the tank and you would be best off re-using the one currently fitted to your vehicle.

google search for a GEMS unit:

can't find one of the single hose THOR type but with a bit of luck yours will fit.:)

[Scouse]

This is the tank from Gumtree (I assume the one Keithy is referring to):
http://www.aulro.com/afvb/attachment.php?attachmentid=90721&d=1424070705


and here is mine which I bought as a Thor tank figuring I could adapt it to fit a GEMS or diesel:

http://www.aulro.com/afvb/attachment.php?attachmentid=90723&d=1424071473

The main difference I can see is in the fuel pump fitment. Ron's tank has the same fitment set up as mine so I assume we both have Thor tanks.
I know Ron has had a hard time getting his pump to seal properly & I bet this is why.

To fit a GEMS pump into this tank, the seal needs to have approx. 75% trimmed away as the pump/seal will not fit the aperture. You might have a similar headache fitting a Thor pump into a GEMS tank.


Anyone have a picture of a Thor tank/pump set up?

[p38arover]

Is that tank anywhere near Sydney? If so, maybe we can swap, Keith.

I bought my tank from Hardy Neale in Brisbane. It was intended for/was previously in the P38A that PaulP38A bought off Hardy. Scouse tells me that was a Thor.

[Scouse]

Is that tank anywhere near Sydney? If so, maybe we can swap, Keith.

I don't think he has a 2nd tank to swap ;).

[mtb_gary]

I noticed that Matar Motors in Melbourne also have a long range tank up for sale on eBay. Starting bid $950. It does not say what year the car was that it came out of.

I'm almost certain Thor's don't have a return fuel line, but can't think of anything else.

Looking at the pics that Scouse posted and this one he found on RR.net, it may be that the Thor has a return line but not a breather in the pump.

But what is the small hose that looks about the same size as a vacuum line?

[p38arover]

That tank has the same retaining ring as mine. But I don't know if that's a Thor pump.

http://www.aulro.com/afvb/attachment.php?attachmentid=90725&stc=1&d=1424078966

[bee utey]

That's a Thor pump, the single male fuel line fitting goes into the nylon section to the right and the plugged fitting is a breather. I compared it to the spare D2 Thor assembly I have.

[Scouse]

That eBay tank has had a breather welded onto the side by the looks of it - there's weld residue around the fitting (to my untrained eye).

Thanks for that. I wonder why that screw-in retaining ring will seal a Thor pump but not my GEMS pump. Does the Thor pump use a different sealing ring in the tank to the GEMS?

[Scouse]

Ron, here's the differences between GEMS & Thor pumps:
Rover V8 Fuel Pump - Efi Engines at www.rimmerbros.co.uk (http://www.rimmerbros.co.uk/Item--i-GRID800062)


https://www.aulro.com/afvb/images/imported/2015/02/406.jpg


The P38 pumps are the two on the right hand side. The Thor pump seal appears to fit between the pump & the locking ring.


I wonder if the GEMS pump in the Thor tank would seal better that way?


I might have to buy an NTC5859 & find out.

[p38arover]

I'll see if I can get one of those sealing rings from KLR tomorrow. It would be easier to check on your tank while it's still not fitted.

[Scouse]

To add to the confusion, the workshop manual appears to show the seal sitting under the pump:
http://www.aulro.com/afvb/attachment.php?attachmentid=90732&d=1424086898


This also shows 2 fuel lines at the pump though. The above photo is for "Advanced Evaps" cars which I take to mean Thor models.


A quick look for NTC5859 (Thor pump/tank seal) shows a seal similar in design to NTC5858 (GEMS):
https://www.aulro.com/afvb/images/imported/2015/02/404.jpg


Maybe just ask KLR if you can have a look at a seal - if it goes under the pump, it might be back to square one.


Can you ask if they have an old Thor pump? That way we can do some measurements & see what we might need to do to make it fit.

[Keithy P38]

Thanks Ron. I'm pretty sure old mate is in South Oz (much closer to you than I).

I've told old mate I'll pass up the offer, save to say I haven't been on the forum today...

What are your thoughts mate?

[p38arover]

Brad at KLR said they didn't have any old Thor pumps. He's ordered in a new seal for me. I'll get there today or tomorrow.

[Keithy P38]

If the tank is still there in a month, I'll let you know, perhaps I could have him deliver to you and I might be ok to take your offer of a swap?

A new one is only a couple of hundred dollars more than what he wanted for this one anyway.

[p38arover]

I might have to buy an NTC5859 & find out.

I just checked. I have an NTC5859 in the garage plus another seal which I think is from a diesel. Both are a perfect sliding fit over the neck of the pump.

In the pics, the black ring is the NTC5859. I don't know what model LR the green seal is from.

I wonder what the diameter of the D2/Thor pump is directly below the top flange? One needs to measure there as the neck is tapered on the spare GEMS pump I have in the garage. The diameter of the neck on that pump is 110mm

[bee utey]

Both the D1 and D2 pumps are 110mm diameter just below the top ring. A D2 pump fits into a D1 tank provided the D1 seal is used and the top flange is trimmed to the same slightly smaller diameter of the D1 pump. Their P38 analogues should be the same.

http://www.aulro.com/afvb/attachment.php?attachmentid=90754&stc=1&d=1424154864

D2 pump in D1 tank, D1 clamp ring, D2 seal, D1 seal.

http://www.aulro.com/afvb/attachment.php?attachmentid=90753&stc=1&d=1424154864

D1 pump, D2 pump, slightly wider top flange. D2 pump body is larger and D1 seal is a struggle to fit but it all goes in. You'll need to check the orientation of the outlet pipe versus the sender float as they may foul inside.

As for seals, it seems that the seal type for the original tank should be used even if you swap pumps.

And lastly: A D1 pump in a D2 tank using a D2 seal and clamp ring, looks like it should seal perfectly:

http://www.aulro.com/afvb/attachment.php?attachmentid=90759&stc=1&d=1424155809

[p38arover]

That's brilliant, B-U. Do you know what the green seal I've pictured above is from?

[bee utey]

That's brilliant, B-U. Do you know what the green seal I've pictured above is from?
The green seal looks like the D2 (Thor) seal I played with today. It appears to have the same inwards facing lip and overall height. The one I have is quite perished and somewhat deformed so it's hard to be 100% sure.

BTW with all the pump seals I've dealt with the secret is to place them just under the pump housing top, insert them carefully without lubricant into the tank orifice, then lightly lubricate the pump housing flange with neat detergent and carefully rotate it in. The seal is dead easy to displace from its correct installed position unless the pump housing can ooze slowly through it.

[Scouse]

Their P38 analogues should be the same.I'd like to think so but I think there might be some differences due to the fact that the D2 Thor & P38 Thor use different seals.


If the green seal Ron has shown is a D2 Thor seal, it's quite different in design from the black seal next to it which is a P38 Thor seal.

[p38arover]

I checked with Brad at KLR this arvo, the new seal he has ordered for me is a replacement for NTC5859.

[bee utey]

I'd like to think so but I think there might be some differences due to the fact that the D2 Thor & P38 Thor use different seals.


If the green seal Ron has shown is a D2 Thor seal, it's quite different in design from the black seal next to it which is a P38 Thor seal.


I meant that the pump housings are probably very similar, especially as the D2 housing has two protrusions where the P38 has a breather elbow fitted.

https://www.aulro.com/afvb/

And then you look at the picture of the Thor type long range tank and see that only the top surface of the seal will actually end up doing anything. I built a couple of D2 auxiliary tanks once and made sure the mounting plate had the groove machined in to better engage the second outer lip on the D2 seal. If the P38 Thor tank seal doesn't have the second lip so be it.

Pick your tank, pick your pump and a new seal that fits well enough to work.

[p38arover]

I'm at KLR Auto and have just picked up the new seal WGQ500020 and it looks identical to the green seal except it's black.

I measured the hole in Scouse's fuel tank and it's 111 mm - 1mm bigger than the pump

[p38arover]

I went to BMI (British Motor Imports) and asked if I could look at and photograph a P38A Thor pump.

They were happy to open a box for me. Thank you BMI! :)

In profile, one can see the top of the neck of the pump top is a different shape to the GEMS (and probably D1) pumps. If you look at my pic below then back at Bee utey's pics above you can just make out the shape in Jilden's pic.

[p38arover]

I measured the opening of the old tank, It's 115mm. It still had the seal in it, probably NTC5858. That seal, while of similar appearance, is smaller in diameter than the NTC5859.

I'll measure and photograph later after dinner.

[Pedro_The_Swift]

well?
come on!:p

[p38arover]

Both seals slide on but the old one is a bit tighter. Maybe it has shrunk. The RH one is the old seal.

http://www.aulro.com/afvb/attachment.php?attachmentid=90855&stc=1&d=1424343059

This the opening of the plastic P38A GEMS tank, note the seals fits inside this and is clamped by the red ring. The hole is 114-115mm diameter.

http://www.aulro.com/afvb/attachment.php?attachmentid=90857&stc=1&d=1424343059

This is the opening on the Brown Davis long range tank Scouse and I have. This is Scouse's tank. Note the flat surface on the very thin plate with the 111mm diameter hole in it. Around that hole is a threaded ring. A matching threaded clamping ring screws into this (see below). We believe this is a Thor tank.

http://www.aulro.com/afvb/attachment.php?attachmentid=90858&stc=1&d=1424343059

This is the clamping ring as viewed from the underside. Note the chamfer. Now this, I believe, is the reason the GEMS pump won't seal in the Thor tank.

Having some old pumps to play with, I tried the clamping ring on the top surface of the GEMS fuel pump.

http://www.aulro.com/afvb/attachment.php?attachmentid=90859&stc=1&d=1424343059

The flat edge of the ring barely touches around the periphery of the pump top. In fact, the pump top is also chamfered and this reduces the clamping surface area even more. The chamfers don't match and I can see daylight under the ring. I doubt it's putting even pressure on the mating surface seal I've in place.

The ring is tightened by a special tool which fits into three equidistant holes in the ring. You can see these holes in this pic:

http://www.aulro.com/afvb/attachments/p38a-range-rover/90725d1424078966-fuel-tank-differences-between-gems-thor-p38a-long-range-tank.jpg

What I intend trying with mine is removing the ring and drilling right through so that I can flip the ring over and still be able to tighten it. That will give a lot more surface area for clamping.

I might need to sketch what I mean to explain it.

I won't be able to do much else. I fell over very heavily yesterday whilst helping the neighbour push a loaded trailer up onto his driveway and I broke one finger and tore back the nail on an adjacent finger on my right hand. I'm not sure I can even grip a steering wheel owing to the pain when I try to close my hand. My right shoulder, knee, and elbow are also suffering. :(

I hope the surgery goes well !

I have some dramas going on at the moment as well, just waiting for a definitive diagnosis :(

Steve

[p38arover]

Good news! No surgery needed. It was an avulsion fracture so my finger is in a rigid splint to hold the finger tip until such time that the tendon is reattached. Time 4-8 weeks and it cannot be removed in that time.


I hope you get some good news, too, Steve.

[TheTree]

Ron

Good news mate !

Mine was not so good, I have been diagnosed with thyroid cancer so it's surgery and radiotherapy for me.

Fortunately the remission rates are over 95% for this type of cancer, so I just have to handle the cure as best i can

Steve

Best of luck with your treatment Steve.

Hope it doesn't knock you about too much mate.

X2 there Steve, I hope the treatment goes well

Good news (of sorts) for you Ron. Not sure about that 4-8 week splint though. I don't suppose it's the middle finger? :wasntme:

Jeez, Steve. I hope it all goes well for you and there is a 100% success rate.

Gary, yes! And it's up in the air! :twisted:

Thanks everyone, it will probably slow me down for a while and apparently the radiotherapy can make you feel like crap.

I feel I am in very good hands though, they have been super thorough so far.

Good luck Steve, I'm sure it won't be long before the treatment is a memory and you are back to your best

[p38arover]

Well, after fitting two long range tanks (GEMS and Thor) this weekend (http://www.aulro.com/afvb/p38a-range-rover/222766-p38-central-today.html) we know a bit more about the tank and fuel pump design, but not all. When I download some more pics from my camera, I'll update this post.

https://www.aulro.com/afvb/

In the above pic, the GEMS tank is on the left. Note the Thor tank (right) has a notch at the front of the tank (smaller end). That's to clear the charcoal canister (not fitted in that location on a GEMS).

On the Thor fuel pump (below), the breather is over hard to the RHS of the vehicle, not leaving much room for the breather hose on the long range tank, hence the need to slope the tank upward on that side, rather than the vertical side of the GEMS tank. The GEMS pump is also higher (for what reason we have no real idea, only conjecture) and has the breather further away, thus giving the hose a better exit angle. The GEMS tank also has a short stub pipe welded on for the breather hose.

http://www.aulro.com/afvb/attachments/p38a-range-rover/90843d1424321797-fuel-tank-differences-between-gems-thor-p38a-thor-fuel-pump-top.jpg

GEMS pump:

https://www.aulro.com/afvb/images/imported/2015/07/498.jpg

We had to modify the Thor pump and seal to make it fit. I recall Brown Davis told me that when I queried it many years ago. I just can't find their emailed instructions to confirm it. The Thor pump is bigger in diameter than the GEMS pump. That and the different seal design might explain why Brown Davis used a different locking ring design. I made up tools to tighten both design locking rings.

[p38arover]

Here are the Thor (left) and GEMS pumps oriented as they would be in the tank. You can see the breather on the Thor is much further left and, if you refer to the earlier pic of both tanks, that the Thor pump sits much lower in the tank. Hence the need for an angled wall on the left side of the tank (as viewed above) to allow the breather hose to be fitted.

We have no idea why the Thor pump sits so much lower in the tank than the pump does in the GEMS tank.

Note the different float arm lengths. Why? Is the lower mounting of the pump to make the fuel gauge more accurate?

We had to remove the anti-rotation lug from the Thor pump. See it just below the breather. With it in place the pump won't sit down on the tank sealing surface.

http://www.aulro.com/afvb/attachment.php?attachmentid=96704&stc=1&d=1437352778

[p38arover]

Here are the standard Thor (on left) and GEMS tanks. They are similar but not the same. See, in particular, the pump retaining ring.

If you've ever wondered why it is difficult (impossible) to siphon from a standard tank, Scouse showed me why. The filler inlet goes into the tank then down near the bottom. At the bottom there is a flap, much like one puts on plumbing drains to stop vermin going up into the drain.

[p38arover]

Here's a question about something that has been puzzling me. Look at the photo below and see how the Thor pump is mounted quite low in comparison to the GEMS.

http://www.aulro.com/afvb/attachments/p38a-range-rover/95733d1435568960-fuel-tank-differences-between-gems-thor-bd-fuel-tanks-1.jpg

Noting that the breather is on the fuel pump, how can the tank be completely filled once the breather is fully covered by fuel? Surely filling will slow or stop?

I can see we are going to have to experiment next weekend.

The small breather at the top rear is the roll-over valve. I disconnected the hose connected to it and tried blowing through the hose back toward the filler. It takes a fair bit of pressure to open the vent at the filler end so I'm not sure how well it would vent air when filling the tank. However, I cannot recall if I had the petrol cap off when I tried that.

I'll remove the petrol cap tomorrow and try it again.

FYI, below is the cover over the pump access hole on my P38A. As you can see, I used a bit of floor out of another (wrecked) P38A. I stripped back some of the underbody sealant on that panel and glued on a 25mm (approx) wide strip of closed cell foam around the edge to act as a seal on the joint.

I tried it and there seemed to be no difference to the pressure required to blow through the line with the cap on or off.

The tank was under quite a bit of pressure when I removed the petrol cap

The hole in the floor and the access.

I've been thinking about how well it is sealed. I do the occasional river crossing and I don't want water flowing into the car.

I might redo the sealing tomorrow.

[Scouse]

Noting that the breather is on the fuel pump, how can the tank be completely filled once the breather is fully covered by fuel? Surely filling will slow or stop?The breather on top of the pump is to speed up fuel delivery by venting air from the tank to the top of the filler neck. Once this vent is closed off by fuel, air will need to escape along the filler neck itself, competing with the incoming fuel resulting in an early 'click off'.
The last 10-20 litres in the Thor tank will be slow as a result of the breather being lower down & blocking off earlier than the GEMS.

Well, we found out the tank can't be filled. Pete tried. So Pete and Scouse removed it today to have it modified. Why would an aftermarket tank manufacturer design a tank that can't be filled?

Scouse noticed in an earlier post in this thread that another tank (below) that was for sale on eBay had been modded. Note the blocked off breather on the pump and the extra breather pipe welded on near the filler.


That eBay tank has had a breather welded onto the side by the looks of it - there's weld residue around the fitting (to my untrained eye).

Good pick up there Scouse!

FYI, I just found these docs on Brown Davis' site. There's no link to their docs from their home page but a bit of searching.....

It might be worthwhile grabbing all their LR docs and saving them. These ones are pretty useless compared with their instructions for other vehicles. There are no installation instructions in the docs.
