Fuel Tank gasket - which material?

[rosie]

I have just removed the lid of my diesel fuel tank for cleaning. The cork gasket (2mmthick) is damaged & needs replacing. Can I use any cork sheet or does it have to be some specific gasket-suitable cork? Or would it be better to make a new gasket from nitrile rubber?

Thanks in anticipation

The gasket needs to be diesel proof, to protect against seepage during rough seas. Nitrile rubber is fine, as is a lot of other gasket materials. Some rubbers use oil in their processing, and hence become sticky as "floppy" as result... definite no go
In my experience the best place to get smallish sized gasket sheets is an engineers merchant, who know what materials to use with what.
Failing that, Ebay has plenty of nitrile and cork suppliers

Nitrile rubber is the correct diesel resistant material to use.
Yellow Pages will show your nearest seals and gaskets specialist.

The cork was most likely a nitrile impregnated cork gasket. Is is available but a lot more expensive than simple cork material.
