NO, I have had my Racetronix PNP pump in my car for 4 1/2 years and the stock fuel regulator will keep everything in check. I would rather hav e recommended amount of fuel presure or a little over than run out of fuel pressure and be lean anyday and it is a great replacement pump and comes with plug and play wiring harness, relay setup.
