Wink Buying a used Fuel tank sensor

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

Re: Buying a used Fuel tank sensor

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

Sent from my super awesome outdated Samsung phone while waiting for masakimms# 500mA overdraw draw to catch fire which turd will be blamed for and we will be sitting on dustybumpers tailgate watching the fire and plotting against yommy.

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.
