My 87 GN is not building boost so I am going through it to check the basics. Haven't seen it going over 1-2psi with my analog boost gauge.
Fuel pressure at idle (w/ vac line attached) : 39-40psi
Fuel pressure at idle (w/0 vac line) : same
Should the pressure drop whenever the vacuum is attached? Vacuum at idle is 18.
I replaced regulator with a replacement stock unit and it does the same thing. What should I look for?
