F 150 2WD Pickup V8-351 5.8L (1986)
Bowl Vent Solenoid: Description and Operation
The Fuel Bowl Vent Solenoid Valve, Figure 1 is part of the Evaporative Emission Control System, and is a normally open valve located in the fuel bowl
vent line. The vent solenoid valve closes off the fuel bowl vent line when the engine is running, and it returns to the normally open condition when the
ignition switch is turned off.
NOTE: if lean fuel mixture Is suspected as the cause of a problem, Inspect the bowl vent solenoid valve for proper closing during engine operation. If the
valve leaks or does not close, the carburetor will give a leaner air/fuel mixture.
