Such fluids can cause immediate explosive damage to the engine and possible personal injury. Truck stops have pumps and nozzles designed for larger, heavy-duty trucks. When refueling at truck stops: if the nozzle shuts off repeatedly when refueling, wait 5-10 seconds; then use a slower rate of flow (don't depress the nozzle trigger as far). 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 the 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. An engine that suddenly becomes noisy or operates poorly after a fuel fill could be using substandard fuel (for example, high water content, low cetane rating or gasoline in the fuel). You should purchase diesel fuel from a reputable station that sells a large amount of diesel fuel. Use only clean, approved containers that will prevent the entry of dirt or water whenever you store diesel fuel. Diesel fuel must not be stored in a galvanized container. The fuel will dissolve the zinc in the galvanized container. The zinc will then remain in the fuel. If you run the contaminated fuel through the engine, the zinc will deposit in the fuel injectors causing expensive-to-repair damage. 29 Super Duty (TFA) , enUSA
