What's the best material for making a new fuel tank cap gasket for diesel. I used cork last time but it's shot after a few years. Has anyone tried nitrile? Thanks.

Just buy a new cap, it will have fuel compatible material for the gasket.

I've gone that route and have had the gasket go bad in a short time, same with my portable transfer tank.

Pre Vent brand fuel cap for the portable tank. Sandy Lake for the fuel cap for the tractor.

Cut one from nitrile I had on had. For 190 diesel. Works great, no material breakdown.

I ordered an AGCO gasket. If it's the same as came with a new cap it won't last too long. If it breaks down I will try the nitrile.

Tom-I am already a happy SLI customer of many years.

Thanks all!
