These are the numbers I have on file for the Jeep Liberty CRD in-tank fuel pump. I know the Carter number P76148M is good; that is what I installed in my CRD fuel tank back in May and it fit and has functioned perfectly...only required a slight trimming of the index tab and replaced the float/float arm with the original one. It was very easy to change...
Adding the additional wiring from under the rear seat to the the top of the tank took more time than changing out the assembly...
Pump maintains about 12-14 psig on outlet side of secondary 2 micron CAT filter at all times....
