Best way is either buy one already fabricated or have one fabricated. That way there's no valve in the middle. If this gains anything who knows. But I'd say its the best way as common sense tells me having a valve in the middle of a pipe effects air flow.
vacuum pipe on both ends? but then inbetween you have simply a pipe?
surely i just block the end of the pipe that attaches to the actuator for the egr, that round looking thing on the side of the egr. the end of this pipe i would imagine attaches to the vacuum dist unit
The pipe attaches to the EGR and to the vacuum manifold. It is very important to block it off at the manifold otherwise you'll have a vacuum leak and grannies in their Tazz's will be pulling away from you.
