Alright, simple question, I'm wondering where the vacuum for the Fuel pressure reg is supposed to connect on an EB/XG engine? The vacuum tree at the back of the inlet manifold (direct vacuum) would've been my thought, but the trouble is there's not enough vacuum connections. Because 1 goes to the brake booster, one to the MAP sensor, one is for heater vacuum supply, and that's it, there's no others, do I have the wrong vacuum tree in the back of the manifold?

Cheers, Gab
