Use an anti-gel additive. See Technical Specifications (page 56). 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. • Low fuel operation: If the low fuel pressure message appears when your vehicle is warm and during low fuel tank level operation (near empty), refuel your vehicle. If the message reappears after fueling, see below. If the message does not come back, the low fuel pressure condition was due to low fuel levels in the fuel tank. Normal operation: If the low fuel pressure message appears during normal operation when the engine is fully warm, and fuel level is not low, you must change the fuel filters regardless of the maintenance schedule interval. If replacement of the fuel filter does not remedy the low fuel pressure message during normal operation as defined above, take the vehicle to an authorized dealer. E163360 3.

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 56).
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.
•
Low fuel operation: If the low fuel
pressure message appears when your
vehicle is warm and during low fuel
tank level operation (near empty),
refuel your vehicle. If the message
reappears after fueling, see below. If
the message does not come back, the
low fuel pressure condition was due to
low fuel levels in the fuel tank.
•
Normal operation: If the low fuel
pressure message appears during
normal operation when the engine is
fully warm, and fuel level is not low,
you must change the fuel filters
regardless of the maintenance
schedule interval.
•
If replacement of the fuel filter does
not remedy the low fuel pressure
message during normal operation as
defined above, take the vehicle to an
authorized dealer.
