89 Comanche Pioneer Fuel Tank, Pump and Sending Unit

Help Please, I am getting Confused and Frustrated..... I am looking the replace the Leaking fuel tank in my Short Bed MJ... I have searched and it looks like I need the Spectra Premium JP5B 18 Gal Tank...... I cannot find a listing for a Replacement Fuel Pump with Sending Unit that lists to be for a 1989 Comanche, 4.0 EFI Motor with 18 Gal Tank..... Any Suggestions?

There are new sending units out there. I forget who makes them. What you want is the 23.5 gallon(LWB) sending unit as the 18 and 23.5 gallon tanks share the same unit.

Thanks For the Replies.... I have not had the MJ for long and just added fuel this weekend. Fuel gauge is not working. I noticed the leak just after putting 10 gals of Non Ethanol in at $4.55.....  I got it back on the lift quickly and it appears to be leaking out of the seam on the Drivers Side next to the Chassis or may be above the seam where the fill neck joins the tank.

In addition to replacement units from MTS, TriStarr rebuilds them and does a very good job. I had mine done by them.

I know this isn't classifieds section, but I've got a 2.5 fuel pump assembly i can let go for a modest price.  You'd just need to put a 4.0 pump in it.  Hit me back channel if you want to.
