hey everyone, I'm kinda new to the vw diesel but have been doing alot of research on them. I wanna put an aux pump (lift pump) on it to help the pump. However, I wanna know the fuel pressure that the injection pump creates so i dont hurt the pump with this new pump. I have a 4-7psi pump that i'm going to mount next to the tank and install a regulator at 2 psi. I just wanna know what kinds of pressure is in the lines and whether or not I need the fuel pressure regulator. Please someone let me know on numbers. Thanks. Oh and the pump is a fresh rebuild so I know I dont need the extra pump but I wanna see what it'll do to help.
