hi guys i got a 1995 jeep xj with the 4.0 i replaced just the fuel pump not the sending unit part when i started it, it reads empty i'm little confused any ideas here guys.

PS sorry also forgot to say its reading empty with 20 dollars worth of gas and the low fuel light also is not on.

Did you have any trouble getting it back in the tank? (In other words, did you bang up the float)?

No because i had the tank out on the ground and its also a brand new tank and rollover valves new also.

I am assuming it all worked before....

Could be that the float got damaged, were the wires on the assembly put right, could be a ground issue from the inside also.

yep it all worked before except the ground on the outside of pump was rotted of and i just put new pump body and wiring harness part back there theres only 2 grounds back there and if either doesn't work pump will not start thats how i know cause my jeep before wouldn't start and it was ground wire.

Hmm, 2 grounds? you sure?

I have an 88 so i might be wrong, but there should be only a 3 wire connector... 1 power, 1 for the gauge, and the black for ground.

Are you splicing any wires or using the 2 connectors? (1 from the fuel pump side, 1 from the vehicle)

I tried doing mine piecemeal ...just replacing the pump...then redid to add a regulator...and filter...then fuel gauge stopped working. Did the whole unit last tuesday with new tank straps too. Works like a charm now and . also found the filter floating in the tank so the pump was shot as well. This cured my chugging idle.
Used to be $150-399 on ebay but now I got this one for $40 on ebay..Must be the 21 year old stock is getting dumped. Works like a champ. Too many tiny plastic parts to fool with..Just replace the unit. And be careful assembling it into the tank, you be fine.
