Use the trip odometer as a replacement fuel supply measuring device.
I've had two fords, so far, where the fuel gauge didn't work and I
just used the trip odometer: fill tank full every time and reset
odometer; refill around 200-230 miles.
I also used an old Pontiac one winter that didn't have a trip odometer
and 1/4 on the gauge meant "empty". A station wagon with worse gas
mileage than my pickup!
As for fixing the problem ... I guess replacing the sending units
sounds like a good idea, if you think the labor is worth it. I never
tried to fix it on any of the vehicles I drove since the trip odometer
was good enough for me.
