Fuel Pressure Regulator
Apparently my FPR hasnt been hooked up to any vacuum source. Where does it get vacuum from on an '85 L98? One of the ports at the back of the upper intake?

The front vacuum port of the two on the rear of the plenum connects to the fuel pressure regulator. If you still have your smog pump it also connects to the A.I.R. valves on the front of the engine.
