Install the injector hold-down and injector hold-down
capscrews, but do not tighten.
Inspect the fuel connector. Look for burrs or deformation
around the inlet and outlet sides of the connector.
Check the edge filters for signs of plugging or material
contamination.
Do not reuse a high-pressure fuel connector if debris is
present.
Check for o-ring tearing or deterioration.
Inspect the outlet sealing surface of the high-pressure
connector for wear, an uneven seating surface, or signs of
leakage.
When a high-pressure fuel leak is present, small lines or
cuts in the connector will be eroded into the seating
surface.
The high-pressure connector and injector must be
replaced when the condition is observed.
Install the high-pressure fuel connector making sure the
end of the high-pressure fuel connector is in the injector
inlet port.
Start the high-pressure fuel connector retaining nut and
tighten partially.
Torque Value: 15 N•m [ 133 in-lb ]
