Gas Fuel Regulator by Willy's Carbs
The anodized billet aluminum construction automatically adjusts fuel pressure according to manifold vacuum. At idle or deceleration, when manifold vacuum is high, the regulator opens and drops fuel pressure for clean restarts and keeps the carburetor from flooding or blubbering in the corner. As the throttle is opened, manifold vacuum drops which closes the regulator and raises pressure for proper straightaway fuel mixture. Easy installation - requires a fuel return line and vacuum port (base plate or intake manifold).
Available for Belt Drive and Mechanical pumps.
