Clean any dirt from the fuel pressure dampener (i.e. damper) retainer (clip) and the surrounding area.
Caution:
If the fuel pressure is not relieved as instructed in Steps 7-9, or the dampener is not held in position during the replacement of the dampener
clip, the dampener 0-ring may not seat or seal properly. A damaged or improperly seated 0-ring may result in a fuel leak. A fuel leak in the
presence of an ignition source may result in a fire.
Caution:
Do not remove the fuel dampener from the fuel rail. If the dampener is removed, a fuel dampener kit with a new 0-ring must be installed. If the
dampener and 0-ring is not replaced, a fuel leak may result. Clean dirt and/or debris from dampener cavity and lubricate the new O-ring with
clean engine oil prior to installation of the dampener.
