  1. Inspect the plastic fuel hose and pulsation damper sealing surface for damage and deformation, and replace if necessary.
    • If the quick release connector "O" ring is damaged or has slipped, replace the plastic fuel hose.
  2. Apply a small amount of clean engine oil to the sealing surface of the pulsation damper.
  3. Push the quick release connector straight into the pulsation damper until a click is heard.
  4. Lightly pull and push the quick release connector a few times by hand and verify that it can move 2.0-3.0 mm {0.08-0.11 in}  and it is connected securely.
    • If quick release connector does not move at all, verify that "O" ring is not damaged and slipped, and reconnect the quick release connector.
  5. Attach the lock clip to the quick release connector in the direction of the fuel distributor and lock it, as shown in the figure.
