Fuel and Refueling Note: If you drain the diesel fuel conditioner module while the system is running air will enter into the fuel system. The engine will not operate properly if air enters the system. Note: With fuel tank levels above 3⁄4 tank it may be necessary to loosen the bowl 3 turns before opening the drain. This will actuate an anti-siphon valve at the fuel and water separator inlet and prevent the fuel from siphoning out of the tank. Note: A loose drain valve can allow air to enter the fuel system and cause drivetrain issues. The engine will not operate properly. Be sure that you fully tighten the drain valve. 1. Stop your vehicle and shut off the engine. 2. Locate the diesel fuel conditioner module and place an appropriate container under the drain port. 5. Restart the engine. If the WATER IN FUEL DRAIN FILTER or WATER IN FUEL DRAIN FILTER SEE MANUAL message and light continues to illuminate, have the fuel system checked and repaired. Low Fuel Pressure The engine is equipped with a low fuel pressure detection system. Here are some possible causes if a low fuel pressure message appears in the information display: • Cold start or during cold operation (below 32°F (0°C): If the low fuel pressure message appears during a cold start or up to 10 minutes after the initial cold start, monitor the information display. If the low fuel pressure message disappears and does not re-appear after the engine has fully warmed up, waxed or gelled fuel is what most likely caused the message. Do not use alcohol based additives to correct fuel gelling. This may result in damage to the fuel injectors and systems. Use an anti-gel additive. See Technical Specifications (page 57). E163360 3. Rotate the drain counterclockwise until the O-ring is visible. Allow the diesel fuel conditioner module to drain for approximately 25 seconds or until clean fuel is observed. Rotate the drain clockwise to tighten it. If no liquid drains, there may be a clog in the drain. Have the conditioner module serviced by an authorized dealer. 4. Make sure that you fully tighten the drain valve and then remove the container from under your vehicle. Note: Your customer warranty may be void from using additives that do not meet or exceed Ford specifications. If the low fuel pressure message persistently appears after re-fueling during the cold start and cold operation conditions defined previously and then disappear when the engine has fully warmed up, consider different fuel sources. 18 Super Duty (TFA) , enUSA

Restart the engine. If the WATER IN
FUEL DRAIN FILTER or WATER IN FUEL
DRAIN FILTER SEE MANUAL message
and light continues to illuminate, have
the fuel system checked and repaired.
Low Fuel Pressure
The engine is equipped with a low fuel
pressure detection system. Here are some
possible causes if a low fuel pressure
message appears in the information
display:
•
Cold start or during cold operation
(below 32°F (0°C): If the low fuel
pressure message appears during a
cold start or up to 10 minutes after the
initial cold start, monitor the
information display. If the low fuel
pressure message disappears and does
not re-appear after the engine has fully
warmed up, waxed or gelled fuel is
what most likely caused the message.
Do not use alcohol based additives to
correct fuel gelling. This may result in
damage to the fuel injectors and
systems. Use an anti-gel additive. See
Technical Specifications
(page 57).
Note:
Your customer warranty may be void
from using additives that do not meet or
exceed Ford specifications. If the low fuel
pressure message persistently appears after
re-fueling during the cold start and cold
operation conditions defined previously and
then disappear when the engine has fully
warmed up, consider different fuel sources.
