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.
