Note
♦
To avoid damage to pump, note the following:
♦
Pressure gauge shut-off valve must not remained closed lon‐
ger than 10 seconds during this test.
♦
Start engine without giving gas and run at idle.
♦
Read the pump pressure immediately after starting at idle
speed (have it read by second technician, if necessary).
♦
Because pressure falls over the course of the test, the highest
pressure shown is the decisive measurement.
– Now check delivery pressure.
