I agree. It should be stock pressure. One reason for changing to an adjustable FPR is because the stock one can't bypass enough with an upgraded pump and the car ends up running a little rich, but it's nothing major.

The vacuum hose should be going to one of the top two vacuum ports on the throttle body.


I disagree that the pump always has to be rewired. I've been using a Walboro with the stock wiring for 5+ years now and haven't had an issue. However, some cars may have worse wiring than others. IIRC, the connector is packed with grease to prevent corrosion.
