Opening Pressure Test
- Open tester shutoff valve 1/4 turn from closed position. Slowly depress tester lever and observe gauge. Note pressure at which needle of pressure gauge stops. Some injector nozzles may pop while other injector nozzles may drip (this is not a leak).
- Opening fuel pressure should not fall less than the lowest limit of 1500 psi (105 kg/cm2 ). Replace any injector nozzle which does not meet lowest acceptable pressure. Release tester pressure.
