Does anyone know who manufactures/supplies the fuel pump seal ( https://www.radicalonline.co.uk/products/FP0010-%252d-Fuel-Pump-Seal.html ) for the 20 gallon aluminum tank setup? Mine is folded over and need another.
Should be part of the supplied fuel pump assembly, I think they are used in VW cars. So see if you can find a seal for a Golf or Passat, I’m guessing 1990 - 2010 vintage. I think it would fit.

Those look like a match. Do you know if there are two different sizes of that seal? The one on my pump appears to be a bit too large.
When you say too large, are you talking about the overall diameter?
seals can/do swell over time and get larger.
There are two dimensions, the ID and thickness of the seal. See what the groove height is on the pump and see if the seal is close to that.
Too large in diameter. The seal is "new"in the sense that it was put in the car over the winter along with the aluminum fuel tank.
Garrett,
did you get the seal issue resolved?
I've got a seal coming in the mail. According to Spring Mountain there is only one size of seal they are just difficult to get in without folding or bending. I will update with the process on how it goes getting in.
Well I got the new seal and gave installing it a go tonight. I immediately managed to fold it over.
Any tips on a mechanical shortcut to keep the seal in it's proper form while seating the pump? I'm not sure how to proceed at this point.
First, post a few photos of the seal and the hole where it goes.
This is what I would I would try:
use a light coat of Vaseline on the tank. Place the pump in the hole. using a thin blunt object, Something like a credit card, Push the seal into the grove on the pump where it lives. You have be be patient and do this a little at a time.
Attached are several pictures. Note how the seal sits down in the hole on the second level rather than the first.
The bottom of the pump is wider than the top so the seal has to be installed on the pump first.
The part that is giving me grief is the double layer on the bottom of the seal - when you drop the pump in the hole the second lip catches the outer ring and folds it up.
If wd40 doesn’t work try either dropping it in a pan of boiling water or using a heat gun to shrink the seal slightly
@gwt561324 - get some Teflon plumbing tape and wrap it around the lip of the seal. You might need more than 1 turn/wrap as you will need to get the Teflon tape to stick to itself well enough to hold pressure inwards on the seal lip. Leave a long 'tail' on the Teflon tape so that you can pull on it once the pump/seal is lowered into the cavity.
Once you have done that carefully place the pump into the cavity, and after the seal lip is below the surface (where you say it catches and folds up), then carefully pull on the tail of the Teflon tape - it should simply unwrap from around the seals lip and come out of the hole without pulling the seal lip back out with it......
