^a (1) Return Fuel (2) Mechanical Returnless (3) Electronic Returnless
^b Early model year will be Returnable Fuel

Return fuel systems return fuel to the fuel tank by means of a return line from the fuel rail.
Mechanical returnless fuel systems do not return fuel to the fuel tank by means of a fuel return line. The pressure regulator is mounted on the Fuel Pump Module located in the fuel tank and excess fuel is returned at this point.
Electronic fuel systems do not return fuel to the fuel tank by means of a fuel return line. There is no fuel pressure regulator and pressure is controlled by continuously varying the fuel pump speed through the fuel pump driver module (FPDM).

Description

For additional information on the Fuel Delivery System, refer to Section 1 .

WARNING: FUEL IN THE FUEL SYSTEM REMAINS UNDER HIGH PRESSURE EVEN WHEN THE ENGINE IS NOT RUNNING. TO AVOID INJURY OR FIRE, RELEASE THE FUEL PRESSURE FROM THE FUEL SYSTEM BEFORE DISCONNECTING ANY FUEL LINE. TO RELEASE THE PRESSURE FROM THE SYSTEM PERFORM THE FOLLOWING:

CONNECT THE ROTUNDA FUEL PRESSURE GAUGE T80L-9974-B OR EQUIVALENT AT THE SCHRADER VALVE LOCATED ON THE FUEL RAIL. TESTING KIT VALVE MUST BE CLOSED.
GRADUALLY OPEN THE TESTING KIT VALVE TO RELIEVE FUEL PRESSURE IN THE VEHICLE FUEL SYSTEM AND DRAIN THE FUEL INTO A SUITABLE CONTAINER OR RETURN IT TO THE FUEL TANK.
TO AVOID UNNECESSARY FUEL SPILLAGE AND FIRE HAZARD, ANY TIME FUEL LINES ARE DISCONNECTED, THE IGNITION SWITCH MUST BE IN THE OFF POSITION UNLESS FUEL PUMP OPERATION IS REQUIRED FOR TEST PURPOSES.

CAUTION: Use care to prevent combustion from fuel spillage. No smoking, open flames or any kind of arcing.

SAFE FUEL HANDLING PRACTICES

Gasoline, Methanol and Methanol Blends

FIRE

Report all fires to the appropriate authorities.
Flames from methanol or methanol-gasoline blends can be invisible.
Know the locations of portable fire extinguishers, fire blankets, fire alarms and eye/wash shower facilities. Learn how to use them.
Use a B or AFFF (light water) type fire extinguisher to fight flammable liquid fires.

FIRST AID

If swallowed:

If gasoline has been swallowed, do not induce vomiting. Seek medical attention immediately!
If methanol or a methanol/gasoline blend has been swallowed, induce vomiting under the direction of a physician or Poison Control Center. Seek medical attention immediately!

When overcome by vapors, if safe, move victim to fresh air. If not breathing, give artificial respiration or CPR (Cardiopulmonary Resuscitation) as appropriate. Seek medical attention immediately!
If splashed in eyes, flush with large amounts of water for 15 minutes. Remove contact lenses, if worn. Seek medical attention.
If splashed on skin, remove contaminated clothing. Wash skin thoroughly with soap and water.

HEALTH

All fuels can be harmful or fatal if swallowed.
Be aware, if fuel is swallowed, onset of serious health effects can be delayed 12 to 24 hours.
Fuels and products containing methanol (e.g. windshield washer fluid) can cause blindness if swallowed.
All fuel vapors can be harmful if inhaled.
All fuels can be harmful if absorbed through the skin.
All fuels are irritating to the eyes and respiratory system.
Some fuels made with gasoline contain benzene which is a cancer-causing agent.

HANDLING

Use flammable liquid handling precautions.
Wear chemical goggles and nitrile gloves (additional protective clothing and equipment may be necessary in some instances).
Keep flammable liquids in approved, labeled, closed containers.
Use in well-ventilated areas and control vapors. Be aware that vapors are not visible, are heavier than air, can travel along the floor, and will settle in lower areas.
When transferring flammable liquids, bond the receiving container to the source and ground the source to the earth.
Do not smoke or use heat/spark producing equipment near vapors.
Do not eat, smoke or drink where these products are handled, processed or stored.
Never siphon by mouth.
Wash hands thoroughly after handling any fuel .

SPILLS

Notify the proper authorities in the event of any spill you have not been trained to clean up.
Stop, contain, and clean up small spills with an absorbent material.

Inertia Fuel Shutoff (IFS) Switch — Reset Instructions

WARNING: IF YOU SEE OR SMELL GASOLINE AT ANY TIME OTHER THAN DURING FUELING, DO NOT RESET THE INERTIA FUEL SHUTOFF (IFS) SWITCH.
Turn key off.
Check for fuel leaks in the engine compartment.
If no leak is apparent, reset the IFS switch by pushing the reset button on the top of the switch (refer to Owner Guide for switch location). NOTE: In the closed position, the button can be depressed an additional 1.57 mm (1/16 inch) against a spring.
Turn key to on or start position for a few seconds, then off again.
Again, check for leaking fuel.
