new pump

Hey

Quick question guys i replaced my fuel pump in my 97 XJ and I'm running rich, i'm smelling unburned gas everytime i get out. The question is does my computer have to adjust for the new fuel pump? If so why?

Thanks

You have another issue. Leak? There is nothing the computer needs to relearn when swapping a pump.
