1. Piping for electro-injectors - 2. Common rail - 

3. Piping for rail supply.

The  high-pressure  piping  connects  the  high-pressure
pump, the  rail  (2)  and  the  electro-injectors. Tubing  is  in
metal construction and coupled by means of hexagon nut
axial junctions.

WARNING

The high-pressure system may reach very high pressure
levels:
DO NOT ATTEMPT TO LOOSEN HYDRAULIC CON-
NECTIONS TIGHTENING ITEMS WITH ENGINE RUN-
NING.

Tighten axial junction nuts with a torque of 20 Nm.

WARNING

In case piping removal is necessary DO NOT REUSE IT
AND ALWAYS REPLACE IT WITH NEW PIPING.

A.To rail supply - B. Return flow from rail

1. Rubber holder junction for fuel inflow from pre-filter -

2. Rubber holder junction for fuel outflow to the tank - 

3. Fuel filter.

Engine piping completing the low pressure fuel system is in
metal  construction. Coupling  is  done  using  eye  junctions
secured using hexagonal screws.
Coupling water-tightness is obtained using copper washers.
In  case  piping  removal  is  necessary, replace  washers  with
new ones when reassembling.
Tighten  low-pressure  junction  screws  with  a  torque  of  12
Nm.

VENTING THE AIR FROM THE FUEL FEED
LOOP 

To exhaust air from fuel system, operate the pre-filter man-
ual pump or use a specific electric pump.
Tighten the vent fitting and continue pumping during the ini-
tial start-up phases.
Make sure that the fuel that flows out of the fitting is not dis-
persed in the environment.

CAUTION

Never attempt to vent the high pressure system, as this is
useless and extremely dangerous.
