rubber selant ring for In-tank fuel pump
i have a mondeo fuel pump sitting in my ali field tank.
i need to find a rubber gasket seal for it ( the original one will not work as its part of a much bigger mounting ).
i need to find a rubber ring - petrol resistant that is 95mm IO, and 115mm od. ( basically like a very large tap washer ).
OR, i can use some sort of sealant ?
any suggestions?

Rubber is not fuel resistant. It swells up and breaks up. I have used cork floor tiles and it seems to work ok for me.

found some Nitrile rubber, which says...
One new strip of Nitrile rubber 1 meter long x 160mm wide x 1.5mm thick. Excellent for general sealing applications/gasket making etc, as it is
resistant to most mineral oils, hydrocarbons, fuels, water and a wide range of chemicals. Temperature range -20°C to +115°C
not bad for £8 inc postage.

Some rubber is fuel-proof, some isn't.
The self-sealing rubber fuel tanks used in WW2 relied on this fact. The inner layer was made from fuel-proof rubber, the outer layer was made from
rubber which swelled when in contact with petrol. If a bullet pierced the tank the outer layer self-sealed the tank to an extent (obviously not if it
was a tracer round  ).

Why not use petrol proof gasket compound? I used it on my tank sender panel and it hasn't leaked yet.

Whatever you do don't use silicone gasket......
How do I know this?
well I can tell you that a tiny sliver about the size of a fingernail can swell up enough to completely block your filter, your fuel pump all the
pipes etc etc and i's a bu**er to get back out of your tank - err so I've heard
"That thing you're thinking - it wont be that."
