ABSTRACT:
A fuel system for a diesel engine includes a low pressure pump for supplying fuel to a high pressure pump, the low pressure pump drawing fuel from the outlet of a filter unit having an inlet connected in use to a fuel tank. A reservoir is provided having an outlet connected by restricted passage means to the outlet of the filter unit and an inlet through which fuel can flow to the reservoir and a further outlet through which surplus fuel can flow from the reservoir. Fuel being drawn from the reservoir in the event that the fuel tank is emptied to allow a restricted flow of fuel to the engine, the fuel in the reservoir allowing the engine to be operated at low speed to assist fuel flow from the tank when the latter is re-filled.
