or replacement of parts and assemblies, the system hermetic-
tightness must be checked as follows:
- make sure the filler caps are securely tightened;
- tighten the clamps and threaded joints until hermetic-sealing
is ensured;
- for initial filling of the fuel system, use the priming pump
on the final fuel filter. Air shall be drained through the screw of
the final fuel filter 7 (Fig. 9.18);
- start the engine, and with it running at idle, visually check
the system. Fuel leaks or the wetting of fuel system components
is not be allowed.
for the final fuel filter use BOSCH, 0 450 126 273, shown
in Fig. 9.18.
Heating is controlled automatically using the fuel temperature
sensor 6.
Every 5,000 km remove the sediment from the filter (unscrew
plug 5, drain the settling until pure fuel flow appears, and screw
back the plug).
Every 15,000 km, replace the filter cartridge.
