Use JB Weld! The regular type NOT the quick hardening stuff. Make sure
the area is oil free and cleaned with MEK or Carb Cleaning solvent.

Is this stuff fuel proof? Can a fuel tank leak be sealed the same way from the
outside?

I've fixed small leaks of fuel and oil using Loctite 290. It's a
green, wicking-type fluid that penetrates weld pores and so on and
hardens to form a heat-resistant seal. Good place to use it is on the
valve pushrod tubes in the heads of the small Continentals.
But the joint has to be clean and dry. I use lacquer thinner or
brake cleaner to rinse the joint, and blow it out, several times.
