Warnings
WARNING: Throughout this guide,you will find warnings identified by thewarning symbol. Warnings remind youto be especially careful to reduce the riskof personal injury.
Diesel Engine Information
The diesel engine fuel system is apressurized two-stage filtration systemand consists of:
•A frame-mounted Fuel and WaterSeparator primary filter with an electricfuel pump and water drain
•An engine-mounted secondary fuelfilter
•A fuel injector for each cylinder (8total)
•A high-pressure fuel pump
•A high-pressure fuel rail for eachcylinder bank (2 total)
•Numerous high-pressure pipes fromthe high-pressure pump to the rails,and rails to the injectors
The fuel and water separator removesboth water and impurities from the fuel.The engine-mounted filter filters finerimpurities from the diesel fuel. Theengine-mounted fuel filter and theframe-mounted fuel filter should bechanged at the recommended serviceinterval or when indicated by theinformation display LOW FUEL PRESSUREmessage. See Scheduled Maintenance(page 325).
The fuel and water separator should bedrained at regular intervals (recommendedat every oil change) or when indicated bythe information display and water in fuelindicator light. See Fuel Quality (page108).
Proper fuel filter maintenance and promptwater draining when the water in fuel lightilluminates is essential to prevent injectionequipment damage. Ignoring the water infuel light or the information displaymessage WATER IN FUEL DRAIN FILTERcan cause your vehicle to go into a reducedpower mode.
A frame-mounted electric fuel pumplocated inside the fuel and water separatordraws fuel from the fuel tank to providepressurized fuel to the engine. The fuelpump contains a pressure relief valve foroverpressure protection in the event ofrestricted flow.
The fuel injection system is controlledthrough the powertrain control module.
Engine Protection Mode
Ford diesel engines are equipped withengine protection and emission controlsystems. These systems monitor criticaltemperatures and pressures, and modifyengine operation accordingly. Thesemodified engine performancecharacteristics are normal.

•If all electrical connections are tightand you need assistance to start, SeeJump Starting the Vehicle (page 190).
If engine cranks but won’t start
Prolonged starter cranking (in excess of 10seconds) could cause damage to thestarter motor or the high-pressure fuelpump.
•Check the fuel gauge. You may be outof fuel. If the gauge shows that thereis fuel in the tank, the trouble may bein the electrical system or the fuelsystem. If equipped with an auxiliarytank, be sure that the tank controlswitch is set for the tank with fuel andnot on an empty tank.
•Leaving your ignition key turned to onfor over two minutes without startingmay make starting difficult becausethe glow plugs will cease activation.Reset the system by turning the ignitionkey to off and then back to on again.
Note:If the system is out of fuel and theengine will not start, do not continuecranking the engine. Continued cranking candamage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine tooverheat:
•Lack of coolant
•Dirty cooling system.
•Plugged radiator fins, A/C condenserand/or oil cooler
•Malfunctioning fan drive
•Driving with frozen coolant
•Sticking thermostat
•Overloading or pulling heavy trailersduring hot weather
•Grill or radiator air blockage
•Slipping or missing drive belt
•Plugged or very dirty air filter
If fuses burn out
WARNING: Replacement fuses andcircuit breakers must always be thesame rating as the original equipmentshown. Never replace a fuse or circuitbreaker with one of a higher rating.Higher rated fuses or circuit breakerscould allow circuit overloading in theevent of a circuit malfunction, resultingin severe vehicle damage or personalinjury due to fire.
Burned-out or blown fuses usually indicatean electrical short-circuit, although a fusemay occasionally burn out from vibration.Insert a second fuse. If this fuseimmediately burns out and you cannotlocate the cause, return your vehicle toyour dealer for a circuit check. SeeChanging a Fuse (page 211).
Selective catalytic reduction systemspeed limit and Idle-only modes

SAFETY PRECAUTIONS
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: The fuel system maybe under pressure. If you hear a hissingsound near the fuel filler inlet, do notrefuel until the sound stops. Otherwise,fuel may spray out, which could causeserious personal injury.
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Gasoline may containbenzene, which is a cancer-causingagent.
WARNING: When refueling alwaysshut the engine off and never allowsparks or open flames near the fuel tankfiller valve. Never smoke or use a cellphone while refueling. Fuel vapor isextremely hazardous under certainconditions. Avoid inhaling excess fumes.
WARNING: Flow of fuel through afuel pump nozzle can produce staticelectricity. This can cause a fire if you arefilling an ungrounded fuel container.
WARNING: Stop refueling after thefuel pump nozzle automatically shutsoff for the second time. Failure to followthis will fill the expansion space in thefuel tank and could lead to fueloverflowing.
Observe the following guidelines whenhandling automotive fuel:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Automotive fuels can be harmful orfatal if swallowed. Fuel such asgasoline is highly toxic and ifswallowed can cause death orpermanent injury. If swallowed, call aphysician 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. Ifyou splash fuel in your eyes, removecontact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek propermedical attention could lead topermanent injury.
•Fuels can also be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andwash your skin thoroughly with soapand water. Repeated or prolonged skincontact with fuel liquid or vapor causesskin irritation.
•Be particularly careful if you are taking“Antabuse” or other forms of disulfiramfor the treatment of alcoholism.Breathing gasoline vapors, or skincontact could cause an adversereaction. In sensitive individuals, serious

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 325).
•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.
Look for a label on the fuel pump toconfirm the amount of biodiesel containedin a diesel fuel. Biodiesel content is oftenindicated with the letter B followed by thepercent of biodiesel in the fuel. Forexample, B20 indicates a fuel containing20% biodiesel. Ask the service stationattendant to confirm the biodiesel contentof a diesel fuel if you do not see a label onthe fuel pump.
Biodiesel fuels degrade more easily thandiesel fuels not containing biodiesel andshould not be stored in the fuel tank formore than 1 month. If you plan to park orstore your vehicle for more than 1 month,then you should empty your vehicle fueltank of biodiesel fuel. You should fill thetank with a pure petroleum-based dieselfuel and run your vehicle for a minimum of30 minutes.
Note:Degraded or oxidized biodiesel candamage fuel system seals and plastics andcorrode steel parts.
During cold weather, if you have problemsoperating on biodiesel, you may need touse a diesel fuel with lower biodieselcontent, try another brand, or discontinuethe use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add anyaftermarket additives to your fuel if youuse a high quality diesel fuel that conformsto ASTM industry specifications.Aftermarket additives can damage the fuelinjector system or engine.
Use Motorcraft® cetane booster or anequivalent cetane booster additive if yoususpect fuel has low cetane. UseMotorcraft® anti-gel & performanceimprover or an equivalent additive if thereis fuel gelling.
