ABSTRACT:
A fuel system for an internal combustion engine includes a pumping apparatus having a high pressure pump to which fuel is supplied by a low pressure pump. The low pressure pump draws fuel through a filter unit from a fuel tank. A reservoir chamber is provided above the apparatus and this in use is replenished with fuel through an inlet. The chamber has a restricted outlet communicating with the fuel inlet of the pumping apparatus. In the event that air is drawn into the system in sufficient quantity to stop the engine as for example if the fuel tank is drained of fuel, the fuel in the reservoir chamber flows through the restricted outlet to the fuel inlet of the apparatus to enable the engine to be restarted quickly.
