WILLY’S LOAD RELATED FUEL PRESSURE REGULATOR
with anodized billet aluminum construction automatically adjusts fuel pressure according to manifold vacuum. At idle or deceleration, when manifold vacuum is high, regulator opens and drops fuel pressure for clean restarts and keeps carburetor from flooding or blubbering in corner. As throttle is opened, manifold vacuum drops which closes regulator and raises pressure for proper straightaway fuel mixture. Easy installation – requires fuel return line and vacuum port (base plate or intake manifold). Kit includes everything needed for gas or alcohol, belt-drive or mechanical fuel pumps.
