To check your guage, values should be as follows. When empty the sender gives 0 Ohms, and when full it gives 100 Ohms with 90 Ohms being equivalent to the 4/4 mark on the fuel gauge. Connect your sender wires together and turn on the ign. The guage should show empty. Jim 6147 "painintheass7565" <advantics@xxxx> wrote: >My fuel gage is pegged full all the time.
