3.6 INSPECTION, GALLERY PRESSURE
}
When inspecting the gallery
pressure, fuel will escape. Collect
this fuel, bearing in mind the risk of
fire.
}
Dirt in the fuel system can lead to
significant damage to pump units
and housing.
1. Remove the plug (1) from the fuel fine filter or
from the pump housing.
2. Connect an attenuated liquid pressure
gauge with a range of 0 - 10 bar to the free
connection point.
Note:
Before inspecting the gallery pressure at the
starting speed, the fuses of the UPEC engine
management system must be removed from
the central box before and after ignition to
stop the engine running and avoid fault
messages.
3. Then check the gallery pressure at idling
speed, full load and starting speed and
compare the measured values to the
specified values. See "Technical data".
4. Remove the pressure gauge and fit the
plug (1).
5. Bleed the fuel system.
