I have a problem with the gas gauge on my 86 Osprey. The gauge sticks at about half full, doesn't move until the tank is almost empty, and then drops to show empty.
Any recommendations for a fix? Thanks
Remove the access pie over the aft end of your fuel tank. Remove the sender. Operate the float while observing the fuel gauge. It should register full with the float at it's upper range of travel, empty when at the lower range. A fuel sender works, or sends a signal to the gauge, on resistance, not voltage. If the upper end of it's travel is not giving the proper resistance, then. as Bob said, it's shot.
By removing it, you also find out what kind of sender you have. The type with a lever arm, or the type with a float that slides up and down a shaft.
