    What would cause my low fuel light to remain on, even after filling the
    tank?

    TIA

    Yeah. :) Gague works fine. Reads the gas levels all the way down to
    empty. When I fill the tank, it goes back to full. The light remains on
    all the time, at this point, that's all.

    ==================

    Dented gas tank, or corroded grounding somewhere? Does the guage work at
    all?

    does the level read low too? if so, it could be a rear impact bending a
    baffle inside the tank holding the float still. jacking the vehicle up
    by the tank can cause the same problem too.

    if the level reads ok independent of the low light, it might be a wiring
    problem. electrical problems on the level are either needle hard up for
    open circuit, or off the bottom for closed circuit.

    Maybe it's LOW octane fuel...

    Sorry... couldn't resist.

    Great. Now the damned thing is thinking for itself. :)

  12. Worse than that, it intercepted your email and is coming after you. I am
    safe because of this foil hat I'm wearing.

    replace the fuel sending unit.

    In my 1985 Celica the sender unit had a seperate contact that
    closed when the fuel in the tank got low enough. I suspect the
    1995 Passport uses a similar setup. If this is the situation, then
    the fuel tank will have to be removed and the defective switch
    repair/replaced. It is posible, thoguh unlikely that Honda
    could have used an electronic voltage sensor to trip the light
    when the fuel gauge reads below some set point. Given the
    greater complexity, ie expense, I suspect that Honda went
    with the same basic sensor that my Celica used.
    A diagram of the electronics should show how the light works.
    Removing a fuel tank is not hard, be sure to syphon out as much
    fuel as you can, a 12 gallon tank full of fuel is, awkward!
    IT is not for the faint of heart. Disconnect the battery!
    And when I work on the fuel system, I get my wife to stay
    close by with Halon. IF it was me, I would almost certainly
    ignore the problem.
    Good luck.

    Yeah. I'm thinking about removing the bulb, at this point.

    In my 1985 Celica the sender unit had a seperate contact that
    it's the same unit as the fuel level unit. the tanks aren't bad to
    drop. having a brass punch to remove the retaining ring is another
    thing.
    it's an odd animal since it is an isuzu rodeo.
