Description

The Willy's Carb WCD691 is a fuel pressure regulator designed for alcohol applications using an electric fuel pump. It automatically adjusts fuel pressure based on manifold vacuum to prevent flooding and stumbling at low engine speeds. The regulator opens during deceleration to drop fuel pressure and closes during acceleration to raise it as needed. It is adjustable from 3-5 PSI at idle and 9-10 PSI at wide open throttle.
