Fuel tank differences between GEMS and Thor

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

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.

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?

Ron, here's the differences between GEMS & Thor pumps:

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.

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.

To add to the confusion, the workshop manual appears to show the seal sitting under the pump:

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):

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.

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?

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.

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?

Cheers
