This is a recent purchase/project for me and I have notice that I have a rubber hose coming off my VP 5.0Gi pwtr fuel reservoir (high pressure pump) not going to anything. According to the parts diagram it should have a Impulse Limiter on the end of it. Also I do not know where it connects to. I have also found the fuel pressure is 36 psi instead of 30. Engine seems to be running good after giving it a little attention over the last couple of months.
