ABSTRACT:
A fuel shut-off valve is particularly adapted for fuel systems using alcohol fuel wherein the alcohol fuel is typically pumped via an on-off valve to a fuel injection system and recirculated back to the alcohol fuel tank. The fuel shut-off valve of the invention is located between the fuel pump and the fuel injection system and is adapted to receive excess fuel from the injectors and direct it back to the fuel pump. In addition, a bypass valve arrangement directs fuel from the fuel pump to either the fuel injection system in the on or open position or back to the fuel pump when the valve is closed. The fuel shut-off valve also has a positive locking mechanism which retains the valve in the open or closed position.
