Close the gauge protector valve (0 to 40,000 kPa (0 to 5,800 psi) gauge).
Flush the fuel nozzle that is being tested by pumping the tester for 3 full strokes.
Open the gauge protector valve (0 to 40,000 kPa (0 to 5,800 psi) gauge).
Use a clean cloth to dry the tip and the body of the fuel injector. All test fluid should be wiped from the nozzle assembly.
A clean cloth should be wrapped around the top of the fuel nozzle in order to absorb any internal return leakage.
Calculate the test pressure that will be used for the tip leakage test.Use the fuel nozzle's valve opening pressure, that has been previously recorded, in order to calculate the test pressure for the nozzle that is being tested.
Subtract a value of 1875 kPa (275 psi) from the valve opening pressure that was previously obtained.
Record the result of the calculation as the test pressure that will be used for the tip leakage test.
Slowly apply the test pressure, that has been calculated in Step 6, to the fuel nozzle.
Close the pump isolator valve.
Hold this test pressure for 10 seconds.
Count the number of drops of test fluid that drips from the nozzle during the duration of the test. Open the pump isolator valve in order to release the pressure on the fuel nozzle when the test is completed.Refer to the information that is provided in Table 3 in order to evaluate the results of the test.Note: Ensure that any test fluid that collects on the tip of the fuel nozzle is not fluid leakage from the test fixture.
