13A
The diesel fuel supply system includes a diesel injec-
tion computer and various sensors.
120417
(1) Fuel tank
(2) Dipstick
(3) Electrical diesel fuel reheater
(4) Man ual priming pump
(5) Diesel filter
(6) High pressure pump
(7) Fuel fl ow actuator
(8) Injector rail
(9) Injector rail pressure sensor
(10) Diesel injector
(11) Venturi
IMPORTANT
Loosening a high pressure pipe union when the
engine is running is strictly prohibited.
WARNING
It is forbidden:
-to dismantle the interior of the pump or injectors.
-to remove the pressure sensor from the fuel rail
(because of circuit contamination problems). If the
pressure sensor fails, the pressure sensor, the rail
and the five high pressure pipes must be replaced,
-to dismantle the flow regulator solenoid valve and
the pressure regulator solenoid valve on the high
pressure pump.
