Typical fuel system

Six cylinder engines
Fuel systems vary from application to application, this information is provided for training purposes only.
Fuel (A9) from the tank (A2) leaves the pre-filter (A4) and then passes to the diaphragm type lift pump (A1),
which is driven by an eccentric on the camshaft. Fuel leaves the lift pump under pressure and passes through
a full flow filter (A5) to the fuel injection pump (A8).
Some fuel injection pumps have a self-vent pipe (A7) to remove air from the fuel system back into the fuel tank.
The fuel in the injection pump also lubricates and cools the pump. A fuel heater or cooler may be fitted between
the filter head and filter canister. The pump has a mechanical governor to control the engine speed.
The pumps also have an electrical stop solenoid and an electrically operated cold start advance unit fitted.
The fuel injection pump increases the fuel pressure and injects high-pressure fuel at the correct time and
sequence through pipes to the atomisers (A11). A fuel leak-off rail is fitted to the top of each atomiser and leak-
off fuel (A10), used to lubricate the atomisers, is returned to the fuel tank through a pipe (A3).
