Alcohol Fuel Regulator by Willy's Carbs
Willy's Carb and Dyno load related fuel pressure regulator with anodized billet aluminum construction automatically adjusts fuel pressure according to manifold vacuum. Under high manifold vacuum conditions, Willy's regulator drops fuel pressure for clean restarts and prevents the carburetor from flooding. As the throttle is opened, manifold vacuum drops, which closes the regulator and raises pressure for proper straightaway fuel mixture.
Available for Belt Drive and Mechanical pumps.
