FUEL F E E D C I R C U I T

The main components of the fuel system are as follows: tank, filter, injection pump and injectors.

Fuel flows from tank (6) to injection pump (2) through filter (7). A pump (9) is fitted upstream from fil-

ter (7) to prime the fuel if necessary (e.g., after replacing the fuel filter).

Rotary injection pump (2) ensures injectors (1) are properly supplied with fuel in the firing order

Because of the particular shape of

the tank, an air pocket could form at

the bottom during refuelling which

would prevent the tank from being

completely filled. This is prevented

by pipe (5), which allows air to flow

out from the lowest part to ensure

complete filling of the tank.

7. Fuel filter

8. Fuel outlet line from filter to injection pump

9. Hand-operated priming pump
