Default Re: Leaking gas tank

The issue is that the tank bracket is riveted to the tank and also thru a reinforcing plate. What we have found when restoring these is the tank will have stress cracks radiating out from the rivet holes. What we generally do is remove the bracket, remove the reinforcing plate and weld the cracks and holes in the tank and plate. Then redrill the holes and rivet the bracket onto the tank again. Otherwise the sealer will pull loose as the bracket is vibrated. Then the weep starts again. Even epoxies (i.e.: JB Weld, etc.) can break loose over time.

FWIW, if the repair to the tank is done correctly, -and if a driver is smart about entering the vehicle, it will last forever.
