  • Fuel Sending Unit Gasket Sealant

    I have a gas guage sending unit that is seeping. What has been used as a good sealant for the sending unit?

    Cork gasket material.

    I once sealed one up with sealer out of a tube. I fought clogged fuel lines for several weeks, and even replaced the tank before I'd realized my stupidity.

      definately been there!

      If the original type cork gaskets don't fix it, there is a newer neoprene version. I think corks are 2.50 and neoprene is 3 bucks. I have some if you don't find them.

      I worked on a tank once that would not seal and had to make a dolly to fit inside so I could hammer down the holes which had been stretched from over-torque.

        Thanks, I'll get a neoprene gasket, and no sealant.

            Corks are a one-time use, they shrink immediately upon removal. I've gone to neoprene, in the hopes that I have bought my last tank gaskets.

              Use cork and aviation Form A Gasket. It is gas resistant. Don't over tighten. It is pretty easy to have the neoprene gaskets deform. Just my two cents acquired through experience.

                I used Form a Gasket on my Nash Metropolitan's sending unit gasket and no more problem leakage. Good stuff!

                5brown1...your 2 cents is now up to 4 cents with mine thrown in.

                  We tried the neoprene gasket on my 53 last year and it still leaked. Switched to the cork with aircraft sealer and it fixed it. Be sure to get the special washers as well. They are a one time use part.

                    I too have had problems with the neoprene. I use cork, but spray it with Kopper-Coat sealer or similar.

                      Whats the saying? Insanity is repeating the same thing over and over and expecting a different result?

                      Try this:

                      I worked on a tank once that would not seal and had to make a dolly to fit inside so I could hammer down the holes which had been stretched from over-torque.

                        Big mistake I made on one of those was red silicone engine gasket sealant applied to the gasket on both sides and the screw threads. Seemed like a good idea at the time.

                        But: Gasoline swells it up and turns it into jelly and globs of it fell into the tank where they got sucked into the fuel line and plugged up the filter.

                        After cleaning that all up I put it back together dry I think and no problems since. I think that sender came with a rubber gasket but its been too long since and I am not sure anymore. There are supposed to be copper washers under the screw heads too.

                          I'd be interested in a couple. Have you got the cork or neoprene?

                          Thanks

                            There don't seem to be any neoprene gaskets out there. They are on backorder according to Chuck Collins. Guess I'll get cork, and Form a Gasket.

                              Ebay item, you'd have to check part number?
