Guys, I finally got a chance to attempt to change out the fuel pressure regulator. Now, I am really wondering what regulator you guys are running. When I checked the fuel pressure regulator a few days back, the truck intake fuel rail pressure was reading 50psi. That regulator was part number #800-329(psi rated at 50psi). After speaking to BR3W City, LS1 NOVA & Clyde 65 they advised me that rail pressure need to be ay least 58-60psi. So, I thought that a simple regulator change to part#800-471( psi reated at 62psi) would solve my problem, but the part of the regulator that actually sticks into the fuel rail is too large in diameter. For those of you running the truck intake, what regulator are you using?
