Fuel/Water Separator Filter
Within 10 minutes of vehicle shutdown, turn the
filter drain valve (located on the bottom of the filter
housing) counterclockwise to drain fuel/water;
allow the accumulated water to drain. Leave the
drain valve open until all water and contaminants
have been removed. When clear fuel is visible,
close the drain valve by turning it clockwise.
Upon proper draining of the water from fuel filter
assembly, the Water In Fuel Indicator Light will
remain illuminated for approximately 10 seconds.
If the water was drained while the engine was
running, the Water In Fuel Indicator Light may
remain on for approximately three minutes.
NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the envi-
ronment. Contact an authorized dealer, service
station, or government agency for advice on recy-
cling programs and for where used fluids and
filters can be properly disposed of in your area.
If more than two ounces or 60 ml of fuel have been
drained, follow the directions for Priming If The
Engine Has Run Out Of Fuel Ú page 364.

Diesel fuel will damage blacktop paving

Do not prefill the fuel filter when installing a
new fuel filter. There is a possibility debris
could be introduced into the fuel filter during
this action. It is best to install the filter dry and
allow the in-tank lift pump to prime the fuel
system.
