What fuel pressure should I be seeing at the fuel rail under idle, with, and without, the vac hose to the regulator connected?
I measured 35psi with the vac connected and 41psi without. Is this a little high? Should it be about 36psi without the vac connected? I've been having fuel consumption probs with the car generally running rich.

I was taking my measurements using a digital type gauge on the valve on the fuel rail (I know this may not do the gauge much good but it was only a cheapo one - although it is quite accurate as I checked it against a few other types)

Cheers,

Toby
