Hello. My front fuel tank on my 1996 F-450 Powerstroke most likely has a defective fuel sensor since the tank is full but gauge shows empty. When I unplug the wire near the tank, the gauge jumps to full.

The rear tank shows a reading when I switch to that tank so guessing the switch is working. How would I test the sensor if I took it out of the tank, would a mechanic be able to test it in a shop? Want to make sure that is the culprit before I start throwing money at parts.

I went on E-Bay and looks like this sensor will cost over $150 and would like to know if there is a nationwide parts locator for wrecking yards which might find me one for less money. Thanks

the test is easy with the sender in hand and a multimeter in the other hand ;-)

i would just google it to watch a video and the Ohm specs should be easy to find also

You would have to check the resistance through the sensor

It should read between 10-180ohms I don't remember which way is which but it should be inside that range as u sweep the sender from full to empty.

Bronco GraveYard sells just the sender/float that has the correct resistance and only needs a small tab filed down to fit the old sender assembly and the float arm bent to the same shape as the original float arm. Way under $100.
