Does anyone know if the small vacuum line coming out from the fuel pressure regulator goes directly into the manifold between the throttle body and IACV? 95 Maxima (Federal)
The FPR vacuum hose doesn't go directly to the manifold between the TB and IACV by itself. It connects to vacuum gallery B and shares the vacuum line with the MAP valve.

When I replaced the FPR earlier this year I replaced all those old vacuum hoses with new 5/16" vacuum hose.
