Gas tank leaks when I fill her up

I replaced the gasket around the sending unit with one I made from cork gasket material.  I guess I will probably have to make another.  Is there an additional sealant that is suitable to fix this problem?

    Check your pickup tube at the tank. They can brake loose from the bracket, and they have a gasket also.

    Jason,  use this product from Permatex with the cork/rubber gasket.   It was recommended to me by Tanks Inc & users on the H.A.M.B...

    It does not harden but cures to very tacky level.  Which allows it be taken apart & reassembled without ill effects, which I have done.  It doesn’t take a lot of the product & it will ooze out as you tighten things down.  Put a very thin amount on each side of all the mounting surfaces but keep an eye on how much oozes out as you tighten things down.  If too much comes out on top, then most likely too much came out inside the tank & you’ll want to dismantle it to make sure you get any thing from inside the tank because you don’t want it dripping into the tank & clogging a pickup tube, etc.  

    I used this on my 37’s tank with an 1/8” thick cork rubber gasket for the sending unit, pickup tube & neck, it’s s custom tank so the neck is attached to the tank.  You can see the bright blue product in these photos.

    Thanks fella's.  I will go get some of this as soon as I run some of the gas out of the tank.

    Not to take any thing away from these suggestions , I would also offer several of my friends with Stepdowns have experienced rust out in the TOP of the tank.  Water condensation from the tank will promote rust out in the top of the tank.

    I resolder the pick up tubes, with new tubes if necessary.

    Ken, do you repair pickup tubes only or do you sell any of those that you have already repaired?

    Who is selling the tanks?

    Jason, I recently sent the one in the photo to Steve Salley in MA. He is supposed to send me his old core so I can have another one to re-solder and have ready to send out. So yes, I can send you one in exchange for your old one provided the steel bracket and the brass fitting are re-useable, the tube I can replace if need be. The brass solder tube fitting with the 45 degree male flare is odd in that the hex part is extra long so it can fit in the hex hole in the bracket and be supported. Thus I cannot readily find an exact replacement new at this time. Let me email Steve and make sure he has sent his core to me.

    I just remembered something......it's still winter in MA, and Steve said in his last email to me it was too cold and the snow piled up in front of the garage door,,,,,, might be a while before I get that core back....

    Jason, you are close to Lance Walker, right? He sold me two rebuildable cores. I think I paid him $15 each. You could get one from him and then send it to me if you need one. I will solder it and send back.  I think the Priority Mail for that small package was about $8-9.

    I think I have a spare tube I can send you as a core.  I have to check to see what kind of shape it is in.  All it's doing in NC is raining a lot so I will have an answer in the morning.

    Hey Ken, who sells these repro tanks and how much do they cost?
  • JasonNCJasonNC Posts: 867Expert Adviser
    Ken, I couldn't find the spare pick up tube mainly because my garage is too junky for me to find anything.  I may have thrown it away since the metal tube had rusted real bad at the bottom, but I doubt it as I'm too much of a hoarder.  I'll probably find it six months from now when I'm looking for something else.  I drive 65 miles to Lance's place seems like every other month.  I think we're getting tired of seeing each other.  (Lance, if you're reading this, I may be down to see you soon about a breather for that manifold).
