It had a renix sending unit but the fuel pump part was pieced together from a 94 HO one. Whomever did it it looks like they took the gas gauge float assembly and cut it off and tac welded the other on there was some things done with the wiring too but I have no idea what I'm looking at never dealt with this issue until now and I have had 5 MJs 2 where HO I'm glad all the other sending units held up I was lucky because I happened to save a sending unit and had no idea you can't buy new ones. I will try to get a pic of the old sending unit so you can see what the guy did the gas gauge and everything worked fine?
