Hi all

Just had power engineering do a top job on my 3 door. Was rolling roaded and set up, but they noted my fuel pump was noisey. Got a new one now, but I'm not sure if there is any kind of pressure regulation, or if this one is more efficient will it end up causing the car to run richer.

Basically - when I change the pump, will I need to get the car rolling roaded again??

Cheers for any help!!
