Is there an adjustment on the fuel sending units? I have a 72 and when i FIRST got the car, when I filled up, it would read FULL. Then about a year later when it was full it would read 3/4 full, NOW when i fill it up, it only ready 1/2 a tank.. Thanks! Chaz.
I know when I fill up or both the cars i have they both read 3/4 full could be just the gauge is wearing out maybe? I dont know
Sure sounds like the float has gotten a pinhole in it and partially filled up with gas. New floats are available from AutoKrafters.
