I installed a Racetronix fuel pump kit in my buddies LT1 Camaro that basically adds a fuel pump relay right at the pump. It uses heavier gage wire that runs right to the back of the alternator. This bypasses all the factory wiring eliminating any voltage drop at the pump. I am thinking about making my own harness up to do the same thing in my Blazer. What do you guys think? Overkill?
