Been having problems with my fuel pump/sending unit since i got this sucker.. The current big problem is the o'ring between the unit, tank, and lock ring has failed & leaks pretty bad. Alongside that, the level gauge is reading empty, despute at least 7 gallons in there. My main concern for today, though, is finding a new seal. Any suggestions on finding one? Seen several, but nothing that confirms the fit

'96 XJ, OEM tank

 

You can order the correct o-ring from ebay or rock auto

the pump module should be removed and the fuel pump sender circuit board cleaned as per my instructions

(first ground the sender leads and see if needle pegs)

2 things that will help you, use the archives, serach "96 manuals and 96 fuel pump in search TITLE ad my username awg

You can dowload ALL relevant 96 manuals and i have a partly completed writeup in 96 FP modules

 

Napa has them. They're common as belly buttons.
