What's your favorite diesel-resistant gasket sealant?
This is for the nitrile gasket on a clean-out port on the top of
a small diesel fuel tank.
I wouldn't mind something that worked well for pipe threads, too.

Thanks,

Tom,
Why do you think it needs a sealant in addition to the gasket.
If you are having a distinct problem with the assembly,
there may be some other issue here.
