  • Fuel pump gasket drama

    Hey guys i was just about to start up my tls yesterday for the first time with my motor swap although when i filled the tank all the fuel leaked out. When i originally got the bike it had a rubber gasket that was inserted in the perimeter of the tank opening and a custom made plate with no rubbed attached to it. The plate on the bike when i got it was clearely a custom made plate as 2 of the holes didnt even line up. I puchased a new plate with rubber sealed around the inside of it on ebay and then attched just that with the thought that i would be riding again. My question is do you need a rubber seal as well as the plate with the rubber seal attched to it to properly re install yihr fuel pump. Also the diagram on babbits is showing 2 plates di yiu need 2 or just the one with the rubber inside?

    Are you sure you got an S tank gasket?

    the S usually is 2 piece the R is one piece

    It never ceases to amaze why people ask for advice then when I give it they either ignore it or argue against it.
    But then I don't know all that much about TL's

    wwjd.......what would jimmy do.

      ......I'm not so sure about that.

      I just replaced the fuel pump gasket on my TLS last March, and I used the single piece steel gasket with the vulcanized neoprene inner seal. So far it is working fine. In fact, it is the same gasket style my '98 S has always used.

      Noah, if your '97 S is leaking with a new gasket, then it may be that the sealing surfaces on the tank are damaged, or you may have a 'pre-recall' fuel tank.

      Does your tank have the embossed asterisk on the underside above the air box as shown in the photo below?

        Yes my tank does have that. I went ahead and reused my old gasket and have no leaks. I think i might have got the gasket for an r never know with ebay.... my current setup is a plain fuel pump plate and a plain rubber seal that goes into the fuel tank. Although for some reason 2 of the holes dont match up with my tank. I bought the tank off a wrecker because my original one which also has an asterisk had extreme rust issues.

          My one piece gasket didnt actually even fit snug into the groove around the perimeter

            That would certainly explain the leak.....

              So since 2 of my holes dont match up with the plate does that mean i have a recalled tank?

                Maybe you have the wrong pump plate. Does it match the photos I posted earlier in this thread? Can you post a photo of your plate?

                If your tank has the asterisk impression, it is the new tank. There were no changes made to the tank after that.

                    I had the wrong plate. Unfortuantely i made the mistake of re using the bolts. Before my torque wrench clicked to 3ftp 2 of them stripped on me. Has anyone resolved a problem like this before?
