LINES, FUEL
DESCRIPTION
Also refer to Quick-Connect Fittings.
WARNING: THE FUEL SYSTEM MAY BE UNDER A CONSTANT PRESSURE (EVEN WITH THE ENGINE OFF).
BEFORE SERVICING ANY FUEL SYSTEM HOSES, FITTINGS, LINES, OR MOST COMPONENTS, FUEL SYS-
TEM PRESSURE MUST BE RELEASED. REFER TO THE FUEL SYSTEM PRESSURE RELEASE PROCEDURE.
The lines/tubes/hoses used on fuel injected vehicles are of a special construction. This is due to the higher fuel
pressures and the possibility of contaminated fuel in this system. If it is necessary to replace these lines/tubes/
hoses, only those marked EFM/EFI may be used.
If equipped: The hose clamps used to secure rubber hoses on fuel injected vehicles are of a special rolled edge
construction. This construction is used to prevent the edge of the clamp from cutting into the hose. Only these rolled
edge type clamps may be used in this system. All other types of clamps may cut into the hoses and cause high-
pressure fuel leaks.
Use new original equipment type hose clamps.
FITTING, QUICK CONNECT
DESCRIPTION
Different types of quick-connect fittings are used to attach various fuel system components, lines and tubes. These
are: a single-tab type, a two-tab type or a plastic retainer ring type. Some are equipped with safety latch clips. Some
may require the use of a special tool for disconnection and removal. Refer to Quick-Connect Fittings Removal/In-
stallation for more information.
CAUTION: The interior components (o-rings, clips) of quick-connect fittings are not serviced separately, but
new plastic spacers are available for some types. If service parts are not available, do not attempt to repair
the damaged fitting or fuel line (tube). If repair is necessary, replace the complete fuel line (tube) assembly.
STANDARD PROCEDURE - QUICK-CONNECT FITTINGS
Also refer to Fuel Tubes/Lines/Hoses and Clamps.
Different types of quick-connect fittings are used to attach various fuel system components, lines and tubes. These
are: a single-tab type, a two-tab type or a plastic retainer ring type. Safety latch clips are used on certain compo-
nents/lines. Certain fittings may require use of a special tool for disconnection.
DISCONNECTING
WARNING: THE FUEL SYSTEM IS UNDER A CONSTANT PRESSURE (EVEN WITH ENGINE OFF). BEFORE
SERVICING ANY FUEL SYSTEM HOSE, FITTING OR LINE, FUEL SYSTEM PRESSURE MUST BE RELEASED.
REFER TO FUEL SYSTEM PRESSURE RELEASE PROCEDURE.
CAUTION: The interior components (o-rings, spacers) of some types of quick-connect fitting are not ser-
viced separately. If service parts are not available, do not attempt to repair a damaged fitting or fuel line. If
repair is necessary, replace complete fuel line assembly.
