Anybody got a Ford part number or numbers for the sending units on my 88 F250 with the 7.3L diesel....I'm getting no ohms when checking resistance of the sender on either tank..Both tanks have some fuel in them, not much but some.....Previously got an over full reading on gauge on either tank, and fuel selector valve wasn't switching....Put on another valve, it switches from front to rear, still over full on gauge...Thinking sender units may be toast..Hate to drop the tanks unless I have tooo...

 

if i was you i wouldnt buy new senders they ain't cheap i would rather run it outa fuel and figure up miles then spend alot of money unless you can find a junk truck with good ones in it

 

I believe the fuel gauge shows empty=15 ohms. 160 ohms=full.

Here's the price of the sender from a supporting vendor/dealer.

The dealers don't post part numbers because they know you'll shop around for the lowest price.

I think the rear tank sender and the side tank sender are different. I know on gas engines they are because of the tank shape and tank capacity are different. Don't know about the diesel trucks.
