petcock help please

[userj8670]

The petcock on my 350x tank has seemed to stop working. It doesn't leak, however when in the off position, the fuel still flows from the petcock. The searches I have conducted seem to state leaking fuel from the tank but this is not the case. Please advise!

There is a round rubber gasket inside with 4 holes in it that seals behind the lever. They shrink and wear out over time, causing the problem you describe. If the petcock is riveted together, they don't sell the gasket separately, so its time for a new petcock. It might be possible to drill the rivets out, and source the gasket and screws from another model that has a serviceable petcock, but I've never tried that myself.
