2017 FORD F250 SUPER DUTY fuel pressure

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel sprayand fire.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler inlet, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Automotive fuels can cause seriousinjury or death if misused ormishandled.
Flow of fuel through a fuel pumpnozzle can produce static electricity.This can cause a fire if you are fillingan ungrounded fuel container.
Fuel may contain benzene, which isa cancer-causing agent.
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Observe the following guidelines whenhandling automotive fuel:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Always turn off the vehicle beforerefueling.
•Automotive fuels can be harmful orfatal if swallowed. Fuel such asgasoline is highly toxic and ifswallowed can cause death orpermanent injury. If fuel is swallowed,call a physician immediately, even if nosymptoms are immediately apparent.The toxic effects of fuel may not bevisible for hours.
•Avoid inhaling fuel vapors. Inhaling toomuch fuel vapor of any kind can leadto eye and respiratory tract irritation.In severe cases, excessive or prolongedbreathing of fuel vapor can causeserious illness and permanent injury.
•Avoid getting fuel liquid in your eyes. Iffuel is splashed in the eyes, removecontact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek propermedical attention could lead topermanent injury.

Fuel and Refueling

Vehicles with engines configured for usewith high sulfur diesel fuel are onlyavailable for sale in countries where ultralow sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in a ultra low sulfurdiesel fuel market that are subsequentlyexported to non- ultra low sulfur diesel fuelmarkets will need to be retrofitted (at thecustomer’s expense using Ford authorizeddealer service parts) in order to be reliablyoperated on non- ultra low sulfur dieselfuel.
Biodiesel
WARNINGS
Do not use home heating oil,agricultural fuel, raw fats and oils,waste cooking greases, biodieselfuels greater than 20% or any diesel fuelnot intended for highway use. Damage tothe fuel injection system, engine andexhaust catalyst can occur if an improperfuel is used. Do not add gasoline, gasoholor alcohol to diesel fuel. This practicecreates a serious fire hazard and engineperformance problems.
Do not mix diesel fuel with gasoline,gasohol or alcohol. This could causean explosion resulting in personalinjury.
Do not add gasoline, gasohol oralcohol to diesel fuel. This practicecreates a serious fire hazard resultingin personal injury and engine performanceproblems.
Do not use home heating oil or anydiesel fuel not intended for highwayuse. Damage to the fuel injectionsystem, engine, exhaust catalyst and dieselparticulate filter can occur if an improperfuel is used. Red dye is used to identifyfuels intended for agricultural andnon-highway use.
You may operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.
Biodiesel fuel is a chemically convertedproduct from renewable fuel sources, suchas vegetable oils, animal fats and wastecooking greases.
To help achieve acceptable engineperformance and durability when usingbiodiesel in your vehicle:
•Confirm the biodiesel content of thefuel to be B20 (20% biodiesel) or less
•Only use biodiesel fuel of good qualitythat complies with industry standards
•Follow the recommended servicemaintenance intervals. SeeScheduled Maintenance (page 573).
•Do not store biodiesel fuel in the fueltank for more than 1 month
•Consider changing brands or reducingbiodiesel content if you have coldtemperature fuel gelling issues or afrequent LOW FUEL PRESSUREmessage appearing
•Do NOT use raw oils, fats or wastecooking greases
Use of biodiesel in concentrations greaterthan 20% may cause damage to yourvehicle, including engine and/or exhaustafter-treatment hardware (exhaustcatalyst and particulate filter) failures.Concentrations greater than 20% can alsocause fuel filter restrictions that may resultin a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil isrecommended for fuels with greater than5% biodiesel (B5). Refer to the Specialoperating conditions section under theSchedule Maintenance chapter for moreinformation about oil change intervals andother maintenance when operating onbiodiesel.

Fuel and Refueling

WARNINGS
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Stop refueling after the fuel pumpnozzle automatically shuts off for thesecond time. Failure to follow thiswill fill the expansion space in the fuel tankand could lead to fuel overflowing.
The fuel system may be underpressure. If the fuel filler cap isventing vapor or if you hear a hissingsound, wait until it stops before completelyremoving the fuel filler cap. Otherwise, fuelmay spray out and injure you or others.
If you do not use the proper fuel fillercap, excessive pressure or vacuumin the fuel tank may damage the fuelsystem or cause the fuel cap to disengagein a collision, which may result in possiblepersonal injury.
Note:If you must replace the fuel filler cap,replace it with a fuel filler cap designed foryour vehicle. The vehicle Warranty may bevoid for any damage to the fuel tank or fuelsystem if the correct genuine Ford orMotorcraft® fuel filler cap is not used.
Fueling Tips
If air is allowed to enter the fuel system theengine automatically purges any trappedair. To purge the air sooner: prior to enginestart, prime the system by turning the keyto on for 30 seconds then to off. Repeatthis several times. The engine may runrough and produce white smoke while airis in the system. This is normal.
Use only clean, approved containers thatwill prevent the entry of dirt or waterwhenever you store diesel fuel.
Diesel fuel must not be stored in agalvanized container. The fuel will dissolvethe zinc in the galvanized container. Thezinc will then remain in the fuel. If you runthe contaminated fuel through the engine,the zinc will deposit in the fuel injectorscausing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
Your vehicle has a fuel fill pipe that is ableto accept fuel up to 20 gal (76 L) perminute from an 1.2 in (30 mm)fuel-dispensing nozzle. Pumping fuel atgreater flow rates may result in prematurenozzle shut-off or spit back.
Truck stops have pumps and nozzlesdesigned for larger, heavy-duty trucks.When refueling at truck stops: if the nozzleshuts off repeatedly when refueling, wait5–10 seconds; then use a slower rate offlow, do not depress the nozzle trigger asfar.
Refueling
When fueling your vehicle do the following:
1.Fully open the fuel tank filler door untilit engages and remove the fuel tankfiller cap. The fuel tank filler cap hasan indexed design with a 1/4 turnon/off feature. Carefully turn the fillercap counterclockwise until it spins off.
