2. Pull the plunger out of the unit pump bore
until the gold portion of the plunger is visible
through the retaining clip slot. The shoulder
of the plunger (where the silver-colored and
gold-colored areas meet), will just align with
the bottom of the unit pump housing.
To avoid possible contamination or damage to
the plunger, do not remove the plunger
completely from the unit pump. If the plunger is
inadvertently removed, dip it in clean fuel and
carefully reinstall it into the unit pump bore. Then
check for smooth, free movement of the plunger
in the unit pump bore.

bore as described in step 2, slide the
retaining clip into place. The flat side of the
clip goes into the retaining clip slot.
The plunger must be positioned as described in
step 2 when the clip is installed, or reassembling
the unit pump spring and spring seat will be
difficult, if not impossible.
