Willys Carbs WCD892 Gasoline Fuel Pressure Regulator
Universal Fit, 2-8 Fuel Pressure Rating (psi)
Willy's fuel pressure regulator features a special diaphragm that uses engine vacuum to automatically regulate fuel pressure. At idle or deceleration, when manifold vacuum is high, the fuel regulator opens and drops fuel pressure for clean restarts and keeps carburetor from flooding or blubbering in the corner. As the throttle is opened, manifold vacuum drops which closes the fuel pump regulator and raises pressure for proper straightaway fuel mixture.
This bypass fuel regulator is designed to be used with a piston-style mechanical fuel pump only. Adjustable fuel regulator has a -8 AN O-ring female inlet port and a -8 AN male return fitting. Requires a fuel return line and vacuum port (base plate or intake manifold) for installation.
Gas regulator provides 8 psi at 4500 RPM and 2-5 psi at idle
