Viton or kalrez rubbers will give the best petrol reistance, with nitrile, or polyacrylate, as second choice.

I bought a box of O rings from Screwfix and there's usually something in there to fit my needs

I got mine on Ebay. Just type in Petrol proof rubber and you will find small sheets for sale.

Piece of sheet cork gasket for petrol tank cap seal..

normally a decent "O" ring wound up the threads to the top will do it.......
JUST make sure the breather hole is not affected or the engine will quit due to a partial vacuum in the tank....

How much is a new fuel cap?

 

[angellonewolf]

only £6 but double that with postage as it comes from germany

 

[keithski122]

For £12 I would'nt bother faffing around buying in something that may or may not fix the problem.
