Patent ·
OSTI ID:5284929
This patent describes a fuel system for an internal combustion engine having fuel injection means with cutoff means, relay means connectable to one or more engine sensors and to the cutoff means, a fuel supply tank, an automatic engine air removal and a shut off device located outside the fuel supply tank. The system consists of: housing means forming a fuel chamber having an inlet passage adapted to be connected to the fuel supply having an outlet passage adapted to be connected to the engine fuel injection means; conduit means connected to the outlet passage and extending downwardly therefrom within the fuel chamber, the conduit means having an inlet at its lower end located below the inlet passage and; means within the chamber for sensing the level of fuel therein and for providing a signal to the relay means for stopping the engine when the fuel in the tank becomes exhausted but before the fuel in the chamber reaches a predetermined lower level within the chamber, thereby preventing air from entering the fuel injection means of the engine fuel system and; fluid retainer means at the lower end of the conduit means within the chamber for holding a quantity of fuel and thereby preventing air from entering the conduit means even if the level of fuel in the chamber should fall below the end of the conduit means.
