ABSTRACT:
This fuel filter device serves to eliminate the need for priming a fuel pump and bleed-air from fuel injectors, in the event that the fuel storage tank runs dry, or fuel filters are replaced on a fuel consuming device, which employs a fuel injecting system. Primarily, the device includes a housing, having a floating filter on its interior, which rides on a perforated fuel valve rod. The device also includes a floating ball valve attached to the armature of a solenoid, which is secured to a fuel output fitting in the bottom wall of the housing, and in the event of water in the fuel, the solenoid is actuated, and its armature will pull the ball valve down for positive shut-off of fuel flow.
