    It started a couple weeks ago...when I'd fill up the tank, it would
    show about 1/8 tank less than full. I filled up the tank yesterday,
    because the fuel warning light was on and it was showing about 1/8
    tank remaining, and the gauge has remained at 1/8 tank with the light
    on! Tried shutting down the van, re-starting, etc, but it still shows
    the same.

    Any good ideas on what the problem is? The gauge?...something in the

    The fuel level sensor uses an etched pc board and a sliding contact
    (attached to the float arm) to measure fuel level. The etchings wear out far
    too soon (IMHO) and cause the loss of contact (infinite resistance), which
    makes the gauge read empty and activates the light. Usually there are bad
    spots where the gauge and light seem to go crazy, but then it clears up when
    the sliding contact moves to a good spot. I was able to live with the
    problemm for a fairly long time because the bad spot began at about 3/4 tank
    level and ended around 1/2 tank level. It cleared up when it counted . . .
    at lower tank levels. However, the bad spot kept growing, so I replaced the
    sensor. Not a difficult job, but messy.
