SAFEGUARD FOR FUEL PUMP
A fuel pump system has a start stage pump and a main stage pump. Fuel is supplied to the start stage pump at lower engine speeds. As the engine speed increases, the fuel system restricts fuel to the start stage pump via a pressure regulating valve and the main stage pump takes over. An electronicall...

| description | A fuel pump system has a start stage pump and a main stage pump. Fuel is supplied to the start stage pump at lower engine speeds. As the engine speed increases, the fuel system restricts fuel to the start stage pump via a pressure regulating valve and the main stage pump takes over. An electronically controlled shut-off valve limits the amount of fuel supplied to the pressure regulating valve and, hence, the start stage pump when closed to safeguard against operating the start stage pump at unsafe engine speeds. |
