FORD 2012 F-550 v.3 - Manual (Page 40)

LOW FUEL PRESSURE SEE MANUAL (diesel engine only) — If
this message appears during a cold start or during cold operation 32°F
(0°C) up to 10 minutes after the initial cold start; monitor the message
center and if it disappears and does not re-appear after the engine has
fully warmed up, the low fuel pressure message is most likely caused by
waxed or gelled fuel. To prevent this, use an anti-gel additive. Refer to
your diesel supplement for more information. The 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 message appears when the vehicle is warm
and during low fuel tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate the 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 message appears during normal operation
when the vehicle / engine is fully warm, and fuel level is not low, the
fuel filters must be changed 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, please
take the vehicle to your authorized dealer.
