FORD 2012 F-550 v.2 - Manual (Page 54)

• 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.
