CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an appropri-
ate 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.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the engine
before you drain water from the fuel filter to avoid engine damage.
UNDERBODY MOUNTED FUEL FILTER/WATER SEPARATOR
Draining Fuel/Water Separator
If the “Water in Fuel” indicator light
is illuminated and an audible chime is
heard five times, you should stop the engine and drain the water from the separator.
The drain is located on the bottom of the Fuel Filter and Water Separator assembly
which is located in front of the rear axle above the drive shaft on pick up models. The
Chassis Cab models second filter location is on the frame behind the front axle. The
best access to this water drain valve is from under the vehicle.
• Turn the drain valve (located on the side of the filter) counterclockwise 1 full turn,
then turn the ignition switch to the ON/RUN position to allow any accumulated
water to drain.
• When clean fuel is visible, close the drain and switch the ignition to OFF.
• Refer to the Diesel Supplement at www.ramtrucks.com/en/owners/manuals for
further details.
Underbody Fuel Filter Replacement
1. With the engine off and a drain pan under the fuel filter drain hose, open the water

2. Close the water drain valve and remove the lid using a socket or strap wrench;
rotate counterclockwise for removal. Remove the used o-ring and discard it.
3. Remove the used filter cartridge from the housing and dispose of according to
your local regulations.
