Im going to change the standard fuel pump on our 3dr, we are running at the moment 390 bhp on light blues would it be better to change to a group A pump or stay with the standard item, if i do change as the wiring got to be changed at all.

 

Change the pump to a Group A and change the wiring as well - there's a thread currently in General Discussion with a wiring diagram for the new wiring required, or use the Search function to find one from a previous thread

 

Thanks for the info matey

 

while you're at it, change the fuel filter if it hasn't been changed recently
