Maintenance and Specifications If air is allowed to enter the fuel system (during fuel filter change or if you run out of fuel) the engine will purge the trapped air as it runs. To purge the air sooner: prior to engine start, prime system by turning the key to on for 30 seconds then to off. Repeat this several times. The engine may run rough and produce white smoke while air is in the system. This is normal and should correct itself in a short time. An engine that suddenly becomes noisy or operates poorly after a fuel fill could be using substandard fuel (i.e., high water content, low cetane rating or gasoline in the fuel). Diesel fuel should be purchased from a reputable station which sells a large amount of diesel fuel. Care should be taken whenever diesel fuel is stored. Use only clean, approved containers which will prevent the entry of dirt or water. Diesel fuel must not be stored in a galvanized container. The fuel will dissolve the zinc in a galvanized container. The zinc will then remain in the solution until it is run through the engine where it will be deposited in the fuel injectors causing expensive-to-repair damage. Diesel fuel dispensing nozzle fill rate This truck is equipped with a fuel fill pipe which is able to accept fuel up to 20 gallons per minute from a 11⁄8 fuel dispensing nozzle. Pumping fuel at greater flow rates may result in premature nozzle shut-off or spitback. Fuel filler cap Your fuel tank filler cap has an indexed design with a 1/4 turn on/off feature. When fueling your vehicle: 1. Turn the engine off. 2. Carefully turn the filler cap counterclockwise until it spins off. 3. Pull to remove the cap from the fuel filler pipe. 4. To install the cap, align the tabs on the cap with the notches on the filler pipe. 5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once. If you must replace the fuel filler cap, replace it with a fuel filler cap that is designed for your vehicle. The vehicle warranty may be void for any damage to the fuel tank or fuel system if the correct genuine Ford or Motorcraft௡ fuel filler cap is not used. 25 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
