Fuel Pressure

To avoid splashing gasoline, wrap fuel supply connector with a rag. Loosen fitting of connector gradually to release pressure. Connect Pressure Gauge (.0141) between fuel supply connector and distributor pipe. Disconnect hose linking fuel pressure regulator and intake manifold. Operate pumps using by-pass harness switch. Fuel pressure should be 33.3-39.2 psi (2.3-2.7 kg/cm2 ). If pressure is incorrect or drops after engine has started, see INCORRECT FUEL PRESSURE.
