Measuring System Pressure
10.
With fuel pumps running, measure system pressure.
Reading: 300 kPa (43 psi)
If reading is correct, proceed with step 11.
If reading is incorrect, proceed with the next steps.
Checking System Pressure
a. Pressure to high:
Remove electrical lead between terminals 30 and 87/2.
Remove fuel return pipe from pressure regulator and blow through it. Repair or replace if restricted and retest.
Remove vacuum hose from pressure regulator and blow through it. Repair or replace if restricted and retest.
If both lines are free of restriction and fuel pressure remains to high, replace and retest with new fuel pressure regulator.
Checking System Pressure
b. Pressure to low:
Pinch fuel return line with hand and check pressure increase.
