My fuel gauge was having intermittent problems reading correctly, and lately has been stuck on empty. So I pulled the sender harness off the tank to check it out. Harness disconnected and key on, it will peg the gauge past full. When I reconnect the harness and key on, it goes back to empty. So apparently the gauge is functioning ok... I have three wires going into the harness. A pink positive coming from the fuel relay (to power the in tank pump?), a yellow sending (positive?) wire coming from the gauge, and a black chassis ground. If I jump the yellow and black with the key on, it should return the gauge back to empty correct? What's my next step besides dropping the tank to inspect the sender unit?
I have read that the float can develop a hole and fill with fuel causing it to sink. The tank has been replaced twice since new due to rust (in the family since 87!) I'm not sure if the sender was ever replaced though
