Removal and Installation: Installation

• Carefully install new O-rings, including the one used with the fuel damper.
• Lubricate O-rings by lightly coating with new engine oil.
• Be careful not to damage the O-rings and surfaces for O-ring sealing surfaces. Do not expand or twist O-rings.
• Discard old clips; replace with new ones.
• Position clips in grooves on the fuel injectors.
• Make sure that protrusions of fuel injectors are aligned with cutouts of clips after installation.

• Align the protrusions of the fuel tube assembly with those of the fuel injectors.
• After properly inserting the fuel injectors onto the fuel tube assembly, check that the fuel tube protrusions are engaged with those of fuel injectors, and the flanges of the fuel tube assembly are fully engaged with the clips.
