I'm looking for a sealant or kit to seal brass NPT inserts into a
polyethylene tank. This is a Kitfox header tank that has developed a leak
at one of the inserts. I'm probably going to use Mogas that has ethanol
additives. Any hints, tips, thoughts?

Thanks,
Rob


Tried that, but it appears to be eaten by the ethanol additives from Mogas.

Ethanol will NOT disolve teflon. It is the material of choice for
handling ethanol fuels.

I like locktite 592 thread sealant for jobs like this. It's a teflon
based pipe dope that doesn't dry out.
