Hello all, am running a retro dual point supercharged engine through an Emerald ECU. I am using a Sytec regulator so has the feed, return and supply. Its also got a vacum pipe at the top, which currently is just open to air, ie under no vac pressure. Is this ok or does it need connected to a vacumn? What does the vac do anyway? Am running at aprox 80psi according to the guage thats fitted to it when engine running. Using MPI tank, if any of those details matter!!
I did post last night but think I used incorrect sectoin.
Anyway, the item I am talking about is top right next to the wiper motor. You can see the vac pip sticking out to the right.
