    Default Gas Guage malfunctioning

    I have a 2002 Montana. Just yesterday, the gas guage started
    malfunctioning - reading full when I knew it was below half. It also jumps
    to empty and triggers the low gas warning light. Any ideas?

    very common for that era........gotten much better in last 4
    yrs.........drain tank, remove tank, remove full pump/sender unit, replace
    fuel level sending card, assure proper oper, before installing, use new
    'o' ring.............if MEGA miles on truck u might consider new pump at
    same time (a few hundred bucks)..............kjun
