  • Fuel Tank removal

    1993 Katana 600

    Is there a way to turn off the fuel petcock? Without draining the tank, the gas will start coming out when I pull the fuel lines correct?

    Just looking for a way to minimize the fuel spillage.

    Put it to ON. Fuel shouldn't flow unless vacuum is applied to the vacuum port. If it does your petcock is shot.

        To drain the tank, is it enough to "suck" the vacum hose? or is there a better way?

          A small amount of vacuum is all it really takes, about the same amount placed on a straw if you were drinking a soft drink. No fluid should be coming from that port, so if the hose is clean it should be fine to apply it yourself.

          To quickly empty the tank, I suggest turning the petcock up so that it is above the fuel level, removing the petcock, and then draining from that hole into a large catch pan or bucket if you have one.

            I put a plugged line on the front outlet, a three foot line on the rear and propped the tank on the side of my truck bed with the long fuel line going down into my truck's gas tank. Turn the petcock to Prime and wait a bit. Voila! no muss, no fuss, empty tank.
