I've been having fuel issues and my tuner can't tune my car to it's potential until i get more fuel. So i'm going to swap the fuel pump and probably the fuel filter again just in case. I don't know if there is much more i can do. is it easier to take out the back seat and cut through the metal to access it from the top or should i just drop the tank? is there a write up on how to make an access point for the fuel pump?
