Fuel Pressure Question

What should the fuel pressure read on a 95 LT1 with the vacuum compensation line attached to the fuel pressure regulator?

At idle it could be anywhere in the 35-40 range or so. It depends on the vacuum the engine is putting out. That is why it is tested with the vacuum line off.

Thanks. When I tested it I wasn't aware the vacuum compensation lined needed to be removed.
