Opening Pressure Test
- Open tester shutoff valve 1/4 turn. Slowly depress tester lever and observe gauge. Note pressure at which needle of pressure gauge stops. Some injectors may pop while other injectors 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 which does not meet lowest acceptable pressure. Release tester pressure.
