    I got me a bright idea for a valve for riders wanting a cheap fuel reserve!

    Start with any new fuel tank, or THOROUGHLY clean out your existing tank.

    Pour in the amount of WATER(Not gas!) you want as your reserve, be it 16 ounces or whatever. Look into the tank with a flashlight and mark the tank's outside where the liquid levels out.

    Empty the water and drill the tank on that fluid level and a convenient spot to run a 90-degree fitting.

    Braze the fitting into the hole with the nipple facing where you want it to.

    Thoroughly clean tank and check for leak at the fitting.

    Run the fuel line from this fitting to the carb.

    Now cut the fuel line and install a tee-fitting.

    Run the third fuel line from tee-fitting to the tank's petcock. Keep petcock closed.

    Fill tank with fuel, start engine and enjoy the drive.

    When engine runs outa fuel or starts sputtering, reach down and turn the petcock lever.

    VOILA! Reserve fuel!

    You'll have to figure out for yourself how much of a reserve you need.

    Experiment close to home.

    Happy motoring!

    yes -- the good old reserve -- as seen on many motorcycles
    those little Honda's I used to ride until they ran out of gas often
    then that reserve would take me a long ways

    reason I am posting here -- for safety reason
    when mentioning brazeing or welding on a gas tank that has been used for gas already
    there are safety steps to be followed -- no boom boom

    ride that thing

    It's actually quite a good idea, once the safety issue is taken care of.

    But I'd say you don't need to go through the trouble of measuring exactly so-many ounces. Just choose a mount spot and you're safe from pedaling involuntarily.

    Bluegoatwoods, as the bank robber stated while looking down the barrel of Dirty Harry's 44-Mag revolver...I gots to know.:detective:

    to calculate accurate reserve miles per gallon figures.

    Yeah, you're right.

    I wasn't taking curiosity for it's own sake into account.

    And that's a bit odd because I'm one of the most curious people around.
    In more ways than one, my wife and kids tell me.....but that's a different matter.
