Fuel tank differences between GEMS and Thor

**Keithy P38** · 10th February 2015, 06:31 PM

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

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

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.

This is the tank from Gumtree (I assume the one Keithy is referring to):

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

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?

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.

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

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.

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.

Dodgy Fuel Gauge (sender) restored...I hope! - Page 2

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