CAUTION:
  • Apply engine oil to the injector O-ring.
  • Do not reuse the used injector O-ring.

CAUTION:
  • Do not reuse the combustion seal.
  • Be careful not to apply engine oil on the combustion seal ring.
CAUTION:
  • Avoid dropping the fuel pipe (including injectors) or bumping it into any hard objects since damage to the internal components may occur. If necessary, visually inspect and confirm proper operation with performance tests prior to reuse.
  • Before installing the injector into the cylinder head, clean the injector hole and avoid contaminants from entering inside the injector hole. When installing the injector, avoid bumping the injector tip into any of the surrounding components since the tip may become damaged from the impact.
  • When fastening the three fuel delivery pipe mounting bolts, fully hand-tighten first, and then tighten in the proper sequence ((1) → (2) → (3)) in several cycles up to the specified torque. The delivery pipe should move less than 1/8 inch (approx. 3 mm), whenever each bolt is tightened.
