FUEL FEED CIRCUIT
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
1-3-4-2.

Vent pipe
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.
