My 1992 HO has an XJ pump... What now?


Recommended Posts

I just got off the phone with the PO of my Comanche, and he gave me the part number for the pump he put in. RE0289S. This comes up on RockAuto as a Cherokee fuel pump. I assume this is why my fuel gauge will only go down to a little over 1/4 tank. Is this gonna cause any problems other than the fuel gauge reading wrong? It seems like every day I take 1 step closer to finishing this truck and then find 10 more steps I didn't know I had. :wall:

Pump will not make a difference, as they are the same. The sender does make a difference. Problem is, nobody makes Comanche senders anymore. the ones some parts stores list as for a Comanche are actually the Cherokee ones.

 

A Cherokee sender does not fit in an OEM tank as the pan in the bottom interferes. This may or may not be your problem. Supposedly they work in an aftermarket tank without the pan.

 

I have never tried myself, this information is from what I read on these forums over the past few years. I also know at least one member has an XJ unit in an aftermarket tank, but don't know if he has any problems with it.

Is the depth of the pump going to make a difference? For example, am I only going to be able to use 18 gallons out of my 23.5 gallon tank before it stops sucking fuel? I've been searching on CC all night but it doesn't seem like many people are running Cherokee pumps.
