Fuel Gauge

[Nigel215]

Last night I parked my truck, But before i turned it off something caught my eye. I look at my fuel gauge and its jumping back and fourth from full to 1/2 tank. I know a lot of people have had problems with their fuel gauges not working at all, it looks like im on my way for that problem. Any one know how i can prevent this from happening or how to fix it now to save me some money down the road?

Mine is doing the same thing. I'm going to change the sending unit. Dealer wants $145 for it, I'm waiting on a guy who might can get it cheaper for me. apparently high carbon content in gas causes problems for a circut. good luck

check and clean the ground to the sending unit. its cheep and simple to do. let us know if that works. i have a feeling about the way the gas tank is grounded.
