  • Welding a sump to a gas tank....

    Hey guys I need to weld a sump to the bottom of a gas tank for my car. I have a dynasty 200 and was wondering what type of rod would be good for this type of job? Thanks guys! By the way both pieces will be new so no fire hazard

    Match the filler to the base metal. Aluminum, stainless, or carbon steel. It is that easy.

      I have been using silocon bronze rod ( not sure of the spelling)
      with very good luck for gas tank sumps

        I'd use ER70S2 1/16" with a 2% 1/16" Tungsten. Good luck!

          What if the tank is aluminum? or PVC

            haha, but seriously, if you have an aluminum tank get an aluminum sump (or make one) and weld as usual, steel use er70s-6

              Then you would need to be an "expert" (that is if you stick with that combo!)

                Solder it

                I have always taken them to the radiator shop and had them soldered.Had three done all the same way.

                  I'd use my 110 mig welder with .023 wire.

                  If looks are a little more important than do what Beebe Motorsports said silicon bronze tig filler.

                    I'd be iffy on soldering it unless the sump was crimped into the tank... but that's just me.
