Checking diesel pressure and flow
It is possible to check the pressure and flow in the low pressure fuel circuit.
The low pressure is delivered by the supercharging pump (electric pump located under the diesel filter designed to
feed the high pressure pump).
SPECIAL TOOLING REQUIRED
Mot. 1311-01
Pressure gauge or
Mot. 1328
Mot. 1311-08 Pressure measuring connector
ESSENTIAL SPECIAL TOOLING
Graduated 2000 ml test tube
CHECK LOW PRESSURE
(SUPERCHARGING PUMP)
Place a "T" connector Mot. 1311-08, to position the
pressure gauge Mot. 1311-01 or Mot. 1328 at the
outlet (S) of the fuel filter or at the HP pump inlet.
Turn the fuel pump using the diagnostic tool or by
directly feeding the pump (each time the ignition is
switched on the low pressure pump is supplied for
30 seconds).
Measure the pressure which should be between
2.5 and 4 bars.CHECK THE FLOW (SUPERCHARGING PUMP)
Make the pump flow into a 2000 ml graduated test
tube. Turn on the ignition to run the pump. The pump is
supplied for 30 seconds if the engine is not started.
The flow read should be 80 to 100 litres/hour
minimum.
IMPORTANT: it is forbidden to measure the
pressure and the flow of the high pressure pump.
