hey guys, i have a 92 d150 with 5.2l magnum i bought as a project there was a small engine bay fire destroyed part of the harness and some vacuum lines ive been able to pick up most of the parts from a local pick a part, however i need help with the fuel pressure regulator on the d/s fuel rail where does the vacuum line run to? looks like its a 90 out of the regulator and then runs to somewhere near the front of the intake manifold?
