  • Leaking Gas Tank 1904 Griffon

    The copper gas tank on my 1904 Griffon motorcycle has a leak in the divider between the fuel tank and the space that holds the battery and trembler coil. It looks like someone has tried to solder the joint, but was unsuccessful. My question is there a way to clean the joint in place and melt the solder that is there into the joint, maybe using a particular flux to clean/prep the joint.

    I am not familiar with the Giffon set up. Like most things prep is half the battle. Need to really clean failed area.

    Could you post a picture?

    I was working on my 1941 Indian 741 tank (steel) using:

    70/30 Bar Solder
    Ruby Red Fluid flux
    200 watt soldering iron

    Another option (and I will be using on my 'repaired' 741 tank)

    Caswell epoxy gas tank liner available at Caswell Coatings
    consider giving it a look.

    All I got for right now. Hopefully others will chime in.
