Replacement Fuel Sending Unit?


Recommended Posts

I've recently bought an '88 Comanche Pioneer, a long bed, automatic, 6 cyl, 4.0.   It runs nicely but there's some things that need fixing. First, the gas gauge always reads empty. The previous owner replaced the gauge and instrument cluster and it makes no difference.   I had a mechanic do some trouble shooting and he's confirmed it's the sending unit and not electical.  But none of his sources can find a replacement Sending Unit.

 

Can anyone recommend a good alternative?  Is there any year/model of Cherokee that has a Sending Unit that will fit an '88 MJ with a 23 gallon tank?

 

Or are a lot of you just living with no gas gauge?  Carrying Jerry cans and refilling from the trip meter?

 

Thanks for your time.

If the gas gauge reads empty all the time, your connection for the sending wire is grounded somewhere. All it took for me was to re-attach the wire to the sending unit inside of the tank, it had broken off and was stuck to the body of the sending unit.

 

Nobody makes a replacement sending unit for the renix era Comanche's, they can be rebuilt but that comes with a cost.

There is a thread on here where somebody modified an XJ sending unit and flipped it around to work on a Comanche.  It would take a little searching, but it was more recent.  The two problems are, the sending units in MJ's face the opposite direction of MJ's, and the float lever arm is longer and shaped a little differently.
