Fuel Pump interchange

Recommended Posts

87-90 2.5L use a smaller pump because of the TBI...

91-95 YJ's use the same pump regadless of the Engine size...


As for an MJ 4.0L they use the same pump...

The sender is different for the MJ so 86-90 or 91-92 if you use the oposite the gauge will be backwards (empty=full)


As for numbers or markings I will have to see if I can dig one up and see if there is anything on them but I do not remember seeing anything...
