What I really need is the fuel pressure regulator thats all the way at the end of the fuel rail (NOT THE REGULAR REGULATOR). Its all the way on the left side of the fuel rail. I just dont know what its really called. Its for a 1991 1.6 Si motor. If you want to get rid of the fuel rail with it that'll also be fine. But what I really only need is that thing all the way on the end of the fuel rail that looks kinda like the fuel pressure regulator. It has a screw at the end of it. Mines leaking.
