    I'm in the process of cleaning out a rusty gas tank and have a replacement petcock that threads into the tank.
    My question is do I Teflon or dope the threads at all before installing?

    Thanks. Jason.

    Sure. Don't use the cheap white tape though.

    Teflon tape is not recommended for gasoline. Breaks down. Yellow tape for gas is natural gas or propane. Believe form a gasket 3 is gasoline stable.

    The best results I've had is making a grommet from marine caulking cotton with a coating of Blue Hylomar jointing compound
