    I have a leaking fuel valve/trap on the bottom of the fuel tank. I have
    replaced the O-ring (p/n 8-27-02aL) on top of the fuel trap (1.25in), but
    fuel now seems to come out of the valve itself. Hugh is offering a new
    valve/trap for $100, but is not able to sell me parts to repair the valve
    itself, as he gets them fully assembled. Question is, is there another
    0-ring in the valve, and what size should I get before disassembling the
    valve and trying to rebuild it ?. By the way my fuel lever can fully rotate
    360 deg from inside the car. I believe that its only supposed to go 180 deg
    from OFF-ON-RESERVE.

    Bill is absolutely correct. To bypass this valve or repair an old tap is an
    unwise choice. Actually this is not a bad part to have a spare in case Huge
    is out just when you need one.

    I removed mine for the same reason. There is a thick gasket inside the valve
    body that goes bad and allows the fuel to leak. I connected a hose directly
    to the threads on the bottom of the tank.

    One word: BOOOOM!

    Behind the round on-off-reserve selector plate that held in place by a
    circlip type affair, there is a thick circular three-holed circular fiber
    flow-director inside of your tap that is probably shot...either dried or
    cracked or warped. I know of no sources for replacements of this single
    critical doohicky, and it ain't exactly something you should try whipping up
    on the kitchen table. Tolerances and materials must be perfect or whatever
    you come up with will leak, with potentially deadly consequences. From the
    fact that your selector can rotate 360 degrees instead of the normal 180, it
    might be surmised that other problems might exist in your fuel tap...perhaps
    the result of a previous owner's attempt to "repair" the tap. Just another
    great reason to lose it now.

    Unless you are the managing director of an engineering unit, the advised
    course of action is to bite that C-Note bullet, call Hugh and just replace a
    leaking fuel tap unit. This is absolutely NOT where you want to
    skimp...doubly so if you happen to have an early model Amphi with the heater
    under the gas tank. Mess around here and you might cap off a pleasant
    afternoon's boating by suddenly finding yourself in the middle of an orange
    fireball heard several zip codes away. So put away that duct tape now...

    Never touch the valve as long as it is dry! They start to leak when they are
    turned once.

    After much trouble I simply dumped the whole tap unit! There are repairing
    kits available here in Germany (you can get every size of these three holes
    gaskets on vintage car markets) but the repair just lasted for a year or so.
    Tried a brand new tap with similar effect.
    Some German Club members use valves from motorcycles, but I gave up all
    hopes and replaced it with an electro magnetic valve directly connected at
    the tank. Most of the Amphicars have an additional magnetic valve anyway. So
    what is the manual valve good for?
    The idea to have a reserve fuel is a bit simple minded in my eyes, your
    clock says early enough when it is time to refill the tank. And 47 litres
    are 47 litres with or without reserve.
    But if you dump the valve take care of the fitting. With the valve comes off
    the little pipe through the fitting hole which give you the imagination of a
    reserve (if you need it hardly one time after years of not using you will
    find out, that it won?t work because of water or dirt on the bottom of the
    tank). On the fitting nut you have to weld a fitting for the petrol tube on
    the lower end and inside you will have to mount a dirt filter which goes
    through the tiny fitting hole of the tank. Those can be found again on
    motorcycles.
    Further you need to add a paper filter in the fuel line. I highly recommend
    to use an electric fuelpump in addition to the mechanical one. Why? Because
    then you get petrol into the carburetor BEFORE the first engine turn, that
    means the engine starts much easier and earlier. Also I?ve seen Amphicars
    stopped on road because the rubber diaphragma from the mechanical pump
    failed from one moment to the other. I don?t want to experience that in the
    water.
    If you are afraid of blow ups there are two more chances to get on fire! One
    is the tankinlet rubber, which usually always leaks as well (never fill the
    tank up to the bottom!) and second is the carburetor. When you park the
    Amphicar with the engine hot, the petrol in the carb starts to boil. The
    steam pressure pushes out the petrol up the accelerating pipe so it drops on
    the shut accelerating flap. This thing is astonishing tied when shut so the
    petrol does not drop further down into the inlet manifold, but finds it way
    through the flaps shafts to the outside of the carb. There it will drop on
    the hot exhaust manifold and fills your car with a deadly mixture of gas and
    oxygene.
    Happy driving,

    Ren?
