Delee Posted April 8, 2021 Share Posted April 8, 2021 Hi I'm redoing a mj with the h.o 4.0 and the tank and pump was wasted so I bought a new tank but I can't find the right sending unit rockauto ,autozone, advance, orileys, nor anything I've seen on the net looks like mine ..my float and strainer point to the left of the inlet hole all others I've seen go to the right and will not fit with the tray in the bottom of tank.. I'm at a loss I've even bought a xj sending unit no luck there either..any help would be nice Link to comment Share on other sites More sharing options...
Torq_Shep Posted April 8, 2021 Share Posted April 8, 2021 There is none. The only reasonable option you have for a 1991 is to send it to https://tristarrradiator.com/ for rebuild. There is a post somewhere of someone hacking together two MKS units to make a 1991 "new" unit but that seems a bit overkill. You could ask if they want to do 2 of the same style and I could send mine in as well =P Maybe get a discount. Link to comment Share on other sites More sharing options...
WahooSteeler Posted April 8, 2021 Share Posted April 8, 2021 Many people have had a very good experience with TriStarr, including myself. Link to comment Share on other sites More sharing options...

bruce9 Posted April 13, 2021 Share Posted April 13, 2021 well, I got screwed. I purchased it from Advanced Auto. received it and just went to install it and found the sending unit and strainer are located on the wrong side. plus the hanger has it sitting a bit shallow so it doesn't locate at all. I called Carter and spoke with them and they quit building the assemblies for these. You can get the pump (higher pressure and GPH than Cherokee?) but no complete assembly. So I need to rebuild the existing assembly. Sorry for the misinformation. And my MJ is a '87 4.0 2wd Link to comment Share on other sites More sharing options...
