Load-Regulated Fuel Pressure Regulator

Regulator automatically adjusts fuel pressure according to manifold vacuum, preventing the carburetor from flooding and stumbling during low engine speeds. Under deceleration, when manifold vacuum is high, regulator opens and drops fuel pressure; under acceleration, manifold vacuum drops and closes regulator, raising fuel pressure as required. Adjustable from 3-5 PSI at idle and 9-10 PSI at wide open throttle. Fully CNC-machined regulator is manufactured from durable, billet aluminum and features a black anodized finish.
