1989 E350 fuel sending unit

msingleton · 11-11-2009, 08:52 AM

I have an E350 with a 460 ci engine and I need a replacement fuel sending unit. It' s for an RV with a 40 gal tank mounted behind the rear axle and includes a fuel pump and it has 3 outlets. I've tried the major parts outlets online but I could only find 2 outlet senders. Tried the RV places online as well with no luck and major chain parts stores. Any ideas where I can find one? Thanks in advance.

So your not looking for a fuel pump just a sending unit??

Welcome to the forum msingleton.

It's somewhat rare for the sending unit to go out
instead of the pump. You've tested the sender itself ?
Many times the real problem is corrosion or broken wires.
Worth a look. Sorry I don't have a lead for you.

Thanks for the welcome. Actually the whole unit is dead. All inputs to the unit read zero ohms regardless of which pins are measured. Got good voltage to the unit and the gauge works fine when jumpered at the tank connector so the wiring is okay. Also found very little corrosion on the connector. I haven't dropped the tank yet - still has ~30 gallons. Guess I'll pull it out and take a look since it's stored for the winter.

A mis-type ? " All inputs to the unit read zero ohms " = dead shorts, not open ?
