Long range fuel tank Disco 4

[DISCO 4]

I need to fit additional fuel storage to my Disco 4, anybody done this?

[ADMIRAL]

Hi Disco4. Not yet but I am just about there. As you have to relocate the spare to fit the extra tank, the choice of spare wheel carrier becomes part of the process.

There are quite a few options. You can pick up on most under the FAQ's at the head of this channel.

I have pretty much decided to go with the Longranger tank. It is 100 litres or thereabouts. There is a 70 odd litre version with a 20-25 litre water tank epoxied to the top, also available from Longranger. Dolium ( Opposite Lock have most of their stuff ) have a nice tank and guard. Due to the the guard though, you lose a fair bit of fuel capacity. The tank is only 80 odd litres.
Your call. It comes down to how much extra fuel you really want.

The spare wheel carriers are also listed under the FAQ's. They include a Kaymar full bumper setup with twin spare wheel carriers, or a variety of bolt through the bumper single carriers. Yes you have to cut a hole in that nice new bumper.

Have a look around and search for other threads. Almost every option has been fitted by someone out there.

Anybody used Outback Accessories fuel tanks

Anybody used Outback Accessories fuel tanks
I have one in my Patrol ( now up for sale ). They work ok, but may not have the finish of the Loneranger or Dolium tank. Nothing wrong with their strength though. Have a talk to your local Opposite Lock store, I think they carry the Outback accessories gear.
I believe it is generally accepted that the D3 and D4 are the same in regard to fitting extra fuel tanks and spare wheel carriers. A lot of threads on the forum on D3 tanks. Some have pics. Do a search.

Chassis is slightly different D3-D4...

Tank manufacturers are modifying them to be universal...

A D3 tank into a D4 hangs low.

A D3 tank into a D4 hangs low.[/Emailed Ric at Longranger yesterday. He believes there is no difference in the chassis mount position for the D3 tanks in the D4.

I am trying to organise supply of a tank at present. If that happens, I will soon know if there is any drama.

[Drover]

Don't forget "Long Range Automotive" 03 97395667.

They do a 110L to suit D3 as a second tank.

[DISCO 4]

Thanks Drover,
I sent of an email to Long Range Automotive as soon as I read your post, still waiting on an answer. I don't need one until late May so no panic YET

Thanks

[DISCO 4]

Long Range Automotive have advised they have a 108 litre tank suitable for the D4

[DISCO 4]

I was advised yesterday by ARB that Long Ranger are currently fitting an auxiliary tank to a D4 and they will confirm when it is finished

[ADMIRAL]

The LongRanger web site has now been changed, and the TA62A tank is now listed for series 111 and 4 models. I have ordered a tank. They are quoting 3 weeks for delivery.

[ADMIRAL]

I am halfway through fitting the LongRanger tank to my D4, and there is an issue.

The tank fits fine, but the change to the filler neck ( for that stupid nozzle blocker ) does mean the filler neck and pipes are different, and those supplied with the tank ( TA62A ) are not compatible. I think LongRanger were looking at the more obvious physical differences, and this one slipped through to the keeper.

I have advised LongRanger, and am currently awaiting a reply.

More data to follow.

[mowog]

Have you had any feedback from Longranger?

[ADMIRAL]

They don't believe there is an issue, but they haven't fitted the tank to a D4 themselves as yet. I haven't had the time to revisit the fit, hopefully this weekend.
LongRanger are under the impression the main tank filler pipe is the same diameter as the D3, even though the top of this pipe has a far longer flare on the D4 than the D3.

The hose used as an adaptor is nearly 4mm too big for the filler pipe. I cannot see how that can be squeezed out with a hose clamp.

I will advise further when I get to it.

[ADMIRAL]

LongRanger have installed a tank in a D4. They noted my concerns and have indicated that apart from the filler neck flare being longer on the D4 ( to accomodate the misfueling device ), all the pipes and filler are of the same dimensions as on the D3. In essence, if they fit the tank to a D4, the fit is the same as a D3.
-The different size of the filler neck pipe to their adaptor tube, they don't see as an issue.
-The LR fuel cap only just fits. It grabs on about the last 1/4 of the available thread. It is evidently the same as the D3 fit. Any other store bought cap is actually a better fit.
- The wiring is ok if you know where to go for the positive pick up, and can keep the wiring protected and hidden.

So not perfect, but satisfactory. I would add, probably not for the inexperienced . If you decide to go down this path, leave it to those who do this type of work for a living.

I am looking a putting a aux fuel tank in the D4 I would like comment on the best choice 104lts 108lts 120lts
Thanks

I went for the opposite lock tank this time around.

On my previous vehicle the fuel line supplied with the long ranger tank (the pickup line for the fuel transfer) corroded and destroyed the fuel pump....very expensive. Out of town (the manufacturer) was aware that this was a problem, but did not see fit to advise owners.....so decided not to go with them this time.

OL tank gravity fees and has a one way valve so won't flow back to the rear tank.

Been very happy with it.

Was told it was about 90litres, but have got over 105litres into it.

Same filler used, and fills up with a normal pump fast enough. Have not tried a high flow pump yet.

Hi all
Isnt there a tank available which replaces the original tank but with increased capacity.
Cheers

My auxillary tank is the Outback tank supplied by Opposite Lock, I think they said it was 109lts, seems fine so far, it's black, so you don't notice it as much as the others that are painted grey.

It also looks to be tucked up out of the way better than mine which is a long ranger.

[minibloodhound]

If I had my chance over, I would go with the opposite lock tank with gravity feed. Similar to what is is standard with the two tanks in my patrol that I used and abused for six years with no problems. With the long ranger tank however, I am now onto my third transfer pump, and even that is now making some wired funky noises during transfer. The strength of it however is fantastic as it has copped plenty of very hard knocks which have decreased its capacity a tad, but still holds fuel!

Hi guys,
I spent quite some time over Easter fitting a Brown Davis 120 ltr Auxillary tank to my D3.
The instructions left quite a lot to be desired!
An example is an angled bracket that fits to the removed heat shield fixing holes, it has a short and long side with the holes in the same position on both sides. The trouble was that no where in the instructions does it tell you which side fits to the chassis or tank!
I had to jack the tank into position a few times to figure out both the above bracket but also the best direction for the outlet hoses to face.
Also the supplied hose fittings for the filler just did not work. I ended up having to purchase a 135 degree radiator hose ( which is not correct for diesel fuel) to temporarily connect the filler as on Easter I could not source an appropiate part. I ended up fitting today a 38mm 135 degree pipe with straight approved hoses.

Work in Progress.

Hose maze. Note the hose right in the centre of the photo at the top.
It may be the exhaust from the Air Compressor?
On the left at the top where the filler neck goes through the body you can see the end of what I presume is the rear diff breather pipe.

https://www.aulro.com/afvb/images/imported/2012/04/905.jpg
More hose maze!

I chose the Brown Davis tank for it's larger capacity.
I'm happy now it's in!

[Graeme]

The exhaust for the suspension system is a 19mm hose that is shown in the WSM as venting to atmosphere inside the top of the compressor box. Perhaps yours has been re-routed.

It was attached to the original filler pipe along with the other smaller breather pipe, you would think that both of these should have some sort of filter attached to them!
The thick one has a sort of slotted vent fitting at the end but no filter.

[Graeme]

The compressor exhaust pipe already has a filter but not at the end.

There is the fuel tank vent pipe and the rear diff breather pipe. The fuel tank vent pipe is meant to have an insect trap in the end. Around here any open pipe is soon used by mud wasps! Actually, I've had to remove mud wasp nests from the rear window glass.

[~Rich~]

The main tank and the auxillary tank vent pipe both attach to the filler neck.

If the small one is the rear diff breather I'm definitely fitting a filter to it!

[Graeme]

The vent pipe or the breather pipe? The breather pipe connects to the top of the filler neck and gets blocked at the tank by fuel when the tank is full to cause back-pressure to cut off the nozzle. The vent pipe vents to atmoshpere near the top of the filler neck and connects to the rollover cut-off valves at the tank. It allows air to be drawn in as the tank empties. A filter seems appropriate.

[mervwho]

Hi Rich.

Is the Brown Davis tank a pump up or gravity feed? They appear to be a very well priced tank for their size.

Thanks
Merv

[~Rich~]

It's a pump, you can see the pump against the wheel arch fitted vertically. It pumps up to the brass fitting you can see near the top of the main tank filler.
I got the tank for just over $1300 as I had it delivered to my mechanic. Discounted 10% plus $80 shipping.

[rmp]

The Brown Davis tank system works well, but for hard offroading hangs too low and will get dented. So mine is being converted and raised, losing a bit of capacity in the process but I'm happy to have only say 100 or even 90 litres in return for more departure angle.

If you aren't into rocks and suchlike it won't be a problem.

[gghaggis]

If you're buying from new, the Opposite Lock one is 80 ltr and doesn't hang down as far.

Gordon

They must have some different sizes Gordon. Mine was supposed to be 90 but have put 105 in it.....based on how much I put in less the factory tank size.

But departure is slightly better than when the tyre was underneath.

Have not yet given it a good smack, but will no doubt one day.

Brett....

[~Rich~]

The Brown Davis does not affect the departure angle, it's higher than the old spare tyre on departure. Where it does hang down is the flat on the bottom which is up about 70 mm from the exhaust lowest point and 30mm above the diffs lowest point. Yes it is a big flat area that may be prone to hitting but the risk is something I am willing to take as I need the maximum range for this trip and will be also carrying 40ltrs in Jerry cans.

Only the Dolium stainless steel tank is 80lts, the Outback tank is 109lts.

[gghaggis]

Um, yes - it's made by Dolium, but (at least over here) you can only buy it through Opposite Lock.

That's right...OL gave me a choice between the two.

I'd never heard of Outback until we had ours installed by OL, have Outback been in WA long??
