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

Thanks,

Hey Rob,

Before you mess up a perfectly good tank....

Just back that brass insert out. It's a pipe thread. Clean up the
mess as best you can.

I've have very good service using the thread sealant that Aircraft
Spruce sells called EZ Turn. I sealed every joint in the fuel system
that used that old white sealant. Some of them were leaking esp. at
the fiberglass wing tanks.

Also try surfing the matronics Kitfox list.
