Sealant for polyethylene fuel tank?

They make sealed end pop rivets. Use them to sandwich some pro-seal between
the tank and an aluminum plate. Tap the plate for the fitting.

The old time fix is to rub the leak with a bar of soap. Seals the leak and
gas won't dissolve it.

I'm looking for a sealant or kit to seal brass NPT inserts into a

Polyethylene is pretty hard to glue anything to.


LEAF has several sizes of rubber "plugs" that a barbed brass fitting
can fit into. Drill a hole, press in the rubber plug, and poke the
fitting into that.

IIRC, I used 1/4" on my plane, but I think they have a 3/8" also.

Other than that?

New Tank?
