fuel sender gasket advice
I have a second hand fuel tank that had already had a sender in it and has been removed.
I am not planning on using a fuel level sender and need to blank tha hole off.
its an ally tank and its fixed in the car already.
What fuel proof material should i use as a gasket to sandwich between the tank and my covering plate
and anyone know where i can get some?
Would some form of silicone sealant be any good?

My sender came with a cork gasket, so I would go for cork.
If using silicon, you'd need to check that it was fuel proof, I'm not too sure that it is, but I could be wrong.

I wondered the same, but if you should use cork, where do you get some that has been bonded together with petrol proof glue?

Defo not silicon. Nowt worse than rogue bits of sealant washing around in the tank - bungs everything up.
I got a pack of cork tiles from diy shop for making gaskets. Would need to trial with fuel first though.
Id say some rubber sheet and cut your own but not sure where from.
Would a big o-ring work?

you can get some sheet and cut out the size - how big a piece do you need as may have some.
Then use red hylomar - blue is not pertol resistant,
beware of silcone and fule - wasnl;t that the stuff in tesco petrol that killed oxygen sensor? although the amounbt of contaminant, if it is in the
selant, that would get into the petro land the in to the O2 sensor would be miniscule.

Cork or neoprene is good in this situation. Not rubber it will swell in contact with fuel.
The thin cork floor tiles are perfect.
You shouldn't need sealant but if you do then the black sensor friendly instant gasket seems to be pretty good.
Experience is what you get when you don't get what you want!!!

Neoprene pond liner!
How thick is it?
O ring MAY work but i can see it being harder to get a decent seal than some of the other methods metioned.
