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 the various fuel system components, lines and tubes.
These are: a single-button type, a two-button type, a pinch type, 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 dis-
connection and removal. Refer to Quick-Connect Fittings Removal/Installation for more information.
CAUTION: Before separating a quick-connect fitting, pay attention to what type of fitting is being used by
referring to Quick-Connect Fitting Removal. This will prevent unnecessary fitting or fitting latch breakage.
CAUTION: The interior components (o-rings, clips) of quick-connect fittings are not serviced separately, but
new plastic spacers and latches 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.
