Circuit leak test

Install the appropriate tool for fuel pressure control
with the pipe fitted with the pressure gauge on the
delivery pipe..
Check during regular operation by placing the ap-
propriate tool between the pump and the injector.
With the battery voltage> 12 V check that the fuel
pressure is 2.5 BAR and that the input current is
1.4 to 1.8 A
With the battery voltage > 12 V, check the pump flow rate by disconnecting from the injector the pipe
equipped with the pressure gauge of the appropriate tool. Get a graded burette with a flow rate of
approximately 1 L. Rotate the pump using the active diagnoses of the palm top computer. Using a pair
of long flat needle-nose pliers, choke the fuel pipe making the pressure stabilise at approx. 2.5 BAR.
Check that within 15 seconds the pump has a flow rate of approx. 110 cm³.
