feed system
(Fig. 9.16)
Fuel runs to high pressure fuel pump 11 from the right side
tank 7 through fine filter 10.
final fuel filter
with hand pumping and water detection sensor
(BOSCH, 0 450 126 273) is shown on Fig. 9.17.
Fuel heater turns on at IGN, when fuel temperature is below
4°C.
Heating is controlled automatically by fuel temperature sensor.
After every 5000 km total kilometres, remove settling from the
filter (unscrew plug 5, drain the settling until pure fuel current
appears, and screw the plug).
Every 15000 km replace the filter cartridge.
For replacement use filter cartridge 1 457 434 310 by BOSCH.
Prior to replacement, remove dirt from the filter outer surface.
When replacing the filter cartridge, prevent ingress of dirt into
the filter body cavity.
for fuel fine filter cartridge replacement proceed as follows::
1. Unscrew housing with cartridge 4 (Fig. 9.17).
2. Lubricate gasket 3 on the housing of the new filter cartridge
with pure diesel fuel oil;
3. Replace with a new housing with a filter element, turning
until spacer 3 contacts with heater 2. Carry out filter material
tightening with FDM 20-25 N•m.
Air release from the fuel feed system.
Air must be released from the system in the following cases:
- the first time the engine is started;
- following long engine idle time;
- upon dismantling of pipelines, filters and pumps;
- upon replacement of the fuel filter cartridge;
- upon complete fuel burn out of the system.
To release air and fill the system with fuel, carrying out of
the following operations is required:
1. Make sure the fuel tanks plugs 1(Fig. 9.16) are tightened
securely. The fuel tank filler plugs are blind and ensure tight
sealing;
2. Loosen the air release plug 7 (Fig. 9.17) on the final fuel
filter (FFF). Using the manual priming pump 1 on the FFF,
fill the main line until air bubbles disappear from the fuel going
from under the air release plug;
3. Tighten air release plug 7;
