    What are the signs that a vacuum operated fuel valve is bad? And is is better to replace it with a stock one,an aftermarket vacuum operated one,or a high-flow non-vacuum one? Thanks,Ben.

    Usually fuel starvation is an indication or leakage.

    Best to go with manual Pingle if you are replacing it.

    And remember to plug the vacume pipe if you replace the petcock with a standard one
    Cut it short and fit a self tapping screw in the end of the pipe

    I would go with The Pingel, they have been making good products for years. To my knowledge there is no way of repairing the vacum petcock

    Pingel for sure. However, if you are the type that doesnt turn off your petcock every time you stop. You may want to start. The stock one needs vacuum to operate. The pingel doesn't and should you develop a leak or if you are carbed, a piece of trash in the float vale could cause a fuel dump.
    Having said all of that, it is a great habit to shut off fuel every time not matter the petcock.
