144
INJECTION
XSARA - XSARA PICASSO
CHECKS : LOW PRESSURE FUEL SUPPLY CIRCUIT
Engines : RHY - RHZ
TOOLS
[1] Ø 10 mm low pressure connector : 4215-T
[2] Ø 8 mm low pressure connector : 4218-T
[3] Pressure gauge for testing boost pressure : 4073-T Tool kit 4073-T
Connect the tool [1] between the booster pump and the fuel filter (white mark at "a"
on the fuel supply pipe).
Connect the tool [2] downstream of the diesel injectors, between the high pressure fuel
pump and the fuel filter (green mark at "b" on the fuel return pipe).
WARNING : Any check of pressure downstream of the fuel filter is PROHIBITED.
Checks on pressure : static.
- Switch on ignition
For 3 seconds (normal functioning):
- Fuel supply pressure shown by the pressure gauge [3] = 1.8 ± 0.4 Bar.
- Fuel return pressure shown by the pressure gauge [3] = 0.5 ± 0.4 Bar.
