  • Fuel tank repair

    Looking for a ‘how to’ and any input from those with experience on whether to bother or not with repair..
    overzealous application of the Jack to lift and hold a very nice condition gas tank into place resulted in a dribble leak. Seems I’ve cracked a seam somewhere on the bottom around the rear curvature of the tank.
    Knew I should have bought that extended range tank from design and development when the exchange rate was near on par…
    thanks

    A tank sealing would do it. I've used POR 15 with great results

      I'd love to get one (or two) of those long range tanks.

      Another option beside POR is Caswell: https://caswellplating.com/caswell-e...l-1-quart.html. I used this on my tank. You will want to clean the tank thoroughly first. Perhaps one is better than the other, but I think treating the tank with any reputable product is better than not doing it.

      I also had a new-ish tank and mine started leaking within a few months of being filled. I think the general wisdom is that it's the alcohol in the gas that does it. I have had no leaks in my tank since using the above stuff.

      Best choice, though, IMHO for a standard tank is one of Pangolin's stainless thanks. It's on my wish list.

        Last year I had 4 BMW motorcycle tanks to clean. I let the Rover do the work and coated them with Redkote. Worked a treat. Click image for larger version

          ‘Tank’ you!
          bought the the POR15 kit shortly after Scott’s post. I’d like to spring for one of those nice, new tanks but foreseeing a rear main seal job sooner than later.

            Wear gloves when messing with POR 15. That stuff stayed on my hands for more than a week

            Put the leftover in an air tight with as little air in there as possible.

                I used nuts, bolts, chain, sand, gravel and simple green

                  I used 300 hex nuts and CLR. Thanks Bud.

                    Man, that POR15 did the trick!

                    all kidding aside, seems like a good time to try and see if I can weld in a USCAR fuel pump mounting ring for an intank efi pump. More to follow.

                      All you need now is 4 drywall screws, 2 to hold the pick up tube in and 2 to keep the board from twisting.
