I askes thig question once before. But I had a brain fart and cant remember what it should be with the fuel pres. reg. vacume line disc.

it will be between 38 hose on and 43 hose off. look at you makeing me half to think on a saturday

So its higher with the hose on?

my bad thanks for pointing that out. no it's not i changed it up there.

just a guess 42 to 46 pounds,,,yes it is higher with the hose off,,,it acts like your accelator pump on a carb,,,gives your fuel injectors a little shot of fuel to match the increase of air volume on any increase to the throttle
