Clean all threads and sealing surfaces very thor-
oughly. Even a small amount of dirt will prevent
the fuel/water separator from sealing, and an air
leak may result.
8.
Install the new filter and grommet assembly and
cover O-ring on the housing.
Position the filter element so the key is lined up
with the keyway on the separator plate of the
housing. Use the arrow on the top of the end-
plate to align the filter. See
. Ensure the
filter element is fully seated by firmly pushing on
the endplate. The filter should not rotate freely.

Install the clear cover and the collar. Simultane-
ously apply downward pressure to the top of the
clear cover until it is seated on the body of the
lower housing and hand tighten the collar until it
no longer spins freely. Using the collar wrench,
tighten the cover 18 lbf·ft (24 N·m). This is
equivalent to rotating the collar clockwise two or
three additional ribs, depending on the specific
filter model.
