WIRING DIAGRAM COMPONENT LOCATIONS
When trying to locate a component in a wiring diagram and you
don't know the specific system where it is located, use this handy
component locator to find the system wiring diagram in which the
component is located. Then, go to that system and locate the component
within the wiring diagram.
For example, if you don't know the specific system in which
the ignition switch is located, look up ignition switch in the wiring
diagram component location tables and go to the appropriate wiring
diagram(s) which contain either full or partial views of the ignition
switch. The full view of the ignition switch is located in Power
Distribution.
The first listing for the component will be the full or most
complete view of the component. Additional listings will be partial
views of the component. Not all components are used on all models.
All components will have a partial view in Ground
Distribution and Power Distribution. Data Link Connectors show
connecting circuits between modules. Alternate names for components
may be listed in wiring diagram component locations tables.

FUEL SYSTEM

fitting and fuel lines are clean. Note location of release tab and
pull tab on disconnect fitting. See Fig. 6.
CAUTION: Release tab must be pressed downward before removing pull tab
or pull tab will be damaged.
2) Press release tab downward. Use screwdriver to pry pull
tab upward until pull tab separates from disconnect fitting. Remove
disconnect fitting from fuel line. Inspect components for damage. If
disconnect fitting is damaged, entire assembly must be replaced, as
only pull tab can be replaced.
3) To install, ensure fuel line and disconnect fitting are
clean. Lubricate fuel line and disconnect fitting with engine oil.
Install disconnect fitting on fuel line until disconnect fitting
bottoms on fuel line.
4) Install NEW pull tab until pull tab locks in disconnect
fitting. DO NOT reuse old pull tab. Pull on fuel line and disconnect
fitting to ensure components are properly locked together. Reconnect
negative battery cables. Start engine and check for leaks.
Removal & Installation (Dual Tab)
1) Disconnect negative battery cables. Ensure disconnect
fitting and fuel lines are clean. Note location of tabs on disconnect
fitting. See Fig. 6.
2) Squeeze both tabs against disconnect fitting. Pull
disconnect fitting from fuel line. The plastic retainer will remain on
the fuel system component being serviced. The "O" rings and spacer
will remain in the disconnect fitting.
3) Inspect components for damage. If disconnect fitting is
damaged, entire assembly must be replaced. The only component that may
be replaced is the plastic retainer. If plastic retainer must be
removed from fuel system component, carefully release the plastic
retainer from the fuel system component using 2 screwdrivers. Inspect
plastic retainer for cracks or damage. Replace plastic retainer if
defective.
4) To install, ensure fuel line and disconnect fitting are
clean. Lubricate fuel line and disconnect fitting with engine oil.

difficult to remove disconnect fitting from fuel line.
2) Firmly push disconnect fitting toward the fuel line while
pushing plastic retainer ring evenly into disconnect fitting. With
plastic retainer ring fully depressed, pull disconnect fitting from
fuel line.
3) Inspect components for damage. If disconnect fitting is
damaged, entire assembly must be replaced.
4) To install, ensure fuel line and disconnect fitting are
clean. Lubricate fuel line and disconnect fitting with engine oil.
Install disconnect fitting on fuel line until click sound is heard.
5) Pull on fuel line and disconnect fitting to ensure
components are properly locked together. Reconnect negative battery
cables. Start engine and check for leaks.
