If the tank has a problem where vacumn is trying to collapse it. It should
still be able to be
filled up. Between opening up the cap and letting the vacumn off. Then the
weight of
16.1 gallons gas return to its normal size. If the tank is damaged from
someone lifting
up on it or what ever. Like Dave's tank it won't read right depending on
where the damage
is and the extent of the damage.
My gauge on my old van once when I ran it almost out of gas got stuck. It
didn't move
until I filled the tank up as much as possible. Then while driving down a
rough road it
shook loose and starting reading correctly.
I'd carry a gallon or so of gas with me when the gauge get lower and test it
again. See how far you can drive and where the needle reads. That way  you
will know if its a glitch or
something you will have to fix. If money and time is tight just use the
odometer. Sounds
like you watch the odometer already.
