FORD 2013 F-550 v.1 - Manual (Page 126)

Diesel Messages Action / Description
LOW FUEL
PRESSURE 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.
