ABSTRACT:
Vent or bleed apparatus for venting or bleeding air from a fuel injection system includes a manual valve and a solenoid controlled valve. The solenoid controlled valve is remotely operated from within the driver's compartment of a vehicle in which the apparatus is installed. The solenoid controlled valve vents or bleeds the air to a return line which extends from the fuel control system to the fuel tank of the vehicle. The bleed apparatus of the present invention replaces a manual bleed valve installed in fuel injection systems in many vehicles.
