Underbody Mounted Fuel Filter Replacement - Diesel Engine - RAM 1500 2020 Owner's Manual

Upon proper draining of the water from the fuel
filter, the "Water In Fuel Indicator Light" will
remain illuminated for approximately
10 seconds.
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
recycling programs and for where used fluids
and filters can be properly disposed of in your
area.
Drain the fuel/water separator filter when the
"Water In Fuel Indicator Light" is ON. Within
10 minutes of vehicle shutdown, turn the filter
drain valve (located on the bottom of the filter
housing) counterclockwise to drain fuel/water,
then turn the ignition switch to the ON position,
and allow any accumulated water to drain.
Leave the drain valve open until all water and
contaminants have been removed. When clean
fuel is visible, close the drain valve by turning it
clockwise, and turn the ignition switch to OFF.
If more than two ounces or 60 milliliters of fuel
have been drained, refer to "Priming If The
Engine Has Run Out Of Fuel" in this chapter.

NOTE:
Using a fuel filter that does not meet the manu-
facturer's filtration and water separating
requirements can severely impact fuel system
life and reliability.
CAUTION!
Diesel fuel will damage blacktop paving

surfaces. Drain the filter into an appro-
priate container.
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.
