The fuel delivery system of a supercharged engine is of paramount importance. As indicated in Part 2 of this series (Sept. '00), we used a state-of-the-art fuel pump and regulator from Aeromotive. The point of this photo is to show the boost-referenced regulator compared with the factory unit. The Aeromotive regulator allows full adjustment and is sensitive to the boost and vacuum created by the engine, altering the fuel pressure proportionately to prevent a lean-out situation from occurring.
