    The car is a 04 mustang gt being built for road racing. I have the holley hp plug and play and have run into an issue with fueling. Do I need to go to a return style fuel system for the Holley? If not, how is it integrated into the holley? No help from Holley. Thanks guys.

    If it doesnt support a returnless setup you can get a GM fuel filter that has the internal fuel pressure regulator. Run a return line from the filter return outlet to the tank. Youll have to pull the hat drill a hole in it and run a fuel line to the bottom of the pickup

    Thanks for the info. I passed the info to my installer and he said that the gm one wont work because of to much psi. I didnt really think that mattered but i am new to fuel systems other than pump upgrades.

    Why not just run a regular return system? I'm assuming this is for the race car.

    Yeah. You are probably right. This is the last time they work on my car. It seems my car gets pushed aside because it is not a Porsche, Vette, Hellcat etc.

    It was probably gonna happen eventually. I was just trying to stay within budget and modify the car system by system like stages. I really wanted to get a fuel cell to go with the fuel system. Oh well it is what it is. Good thing is if I go coyote or decide to use ethanol, I can. Yeah, it is for the race car. Ordered some fuel parts from lethal performance to complete the system.
