    Are you sure the leak is not originating from one of the pressure relief vent tubes?

      I can look, but pretty sure it's not.

      This is a great gas-oil resistant sealant to hold the seal into position when installing. This is the absolute best gasket sealant, as it stays tacky and is sensor-safe and resistant to gasoline, oil, antifreeze, axle lube, kerosene, propane and butane. The best!

        Wonder how it is for removal of threaded parts, and how hard to clean off when parts are disassembled?............MO

        I have used this stuff (Hi Tack) for years. It cleans up very easy with Lacquer Thinner. It never gets completely hard. Ref my post #29. It held up about a year and started leaking again.

        Save yourself the grief and replace your lock ring with an OEM equivalent.

        This is an update. Do not waste your effort. It will leak with using sealer. Been there done it also.

          I replaced my old gas tank with a new aftermarket, using the old ring and the high tack sealant to hold it in place while installing. I tried multiple times without the sealant, but couldn’t keep it into position. Agreed, the new retaining rings are junk.

          I agree, When I changed my tank out the aftermarket ring was not tight, I used the original ring I think I bent up the tank side flanges to make it fit much tighter. I only used the gasket its been 5 years so far so good.

          I just replaced my tank with one from YearOne
          The locking ring was extremely tight
          We even had to fight with it to get it to lock in where we wanted it
