REPAIR INSTRUCTIONS
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, carefully reinstall into
the unit pump bore, then check for smooth, free
movement in the unit pump bore.

3. With the plunger pulled from the unit pump
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.
