Are the vacuum lines the same for a 302 and 351? I pulled the lines from a 302 and it has a line my 351 doesn't have. I have 2 red lines that hook to the manifold on the drivers side near the throttle body and one spot that is capped. The 302 harness has a 3 prong rubber connector with a black hose coming off. Is my 351 missing the black hose or was that only 302.

Thanks for the info. After taking a good look again I do have the hose. It is just attached at another spot near where the other lines are attached.
