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 14 - FUEL SYSTEM/FUEL DELIVERY/QUICK CONNECT FITTING - STANDARD
PROCEDURE)
CAUTION: Before separating a quick-connect fitting, pay attention to whattypeoffittingisbeingusedby
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.

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. Referto fuel system pressure release
procedure.

(tube) assembly.
1. Perform fuel pressure release procedure. Refer to Fuel Pressure Release Procedure.
2. Disconnect negative battery cable from battery.
3. Clean fitting of any foreign material before disassembly.

16.Plastic Retainer Ring Type Fitting:This type of
fitting can be identified by the use of a full-round
plastic retainer ring (4) usually black in color.
a. To release fuel systemcomponent from quick-
connect fitting, firmly push fitting towards com-
ponent being serviced while firmly pushing
plastic retainer ring into fitting (6). With plastic
ring depressed, pull fitting from component.
The plastic retainer ring must be pressed
squarely into fitting body. If this retainer is
cocked during removal, it may be difficult
to disconnect fitting. Use an open-end
wrench on shoulder of plastic retainer ring
to aid in disconnection.
b. After disconnection, plastic retainer ring will
remain with quick-connect fitting connector
body.
c. Inspect fitting connector body, plastic retainer
ring and fuel system component for damage. Replace as necessary.
17.Latch Clips — Type 1:Depending on vehicle
model and engine, 2 different types of safety latch
clips are used. Type-1 (4) is tethered to fuel line
and type-2 is not. A special tool will be necessary
to disconnect fuel line after latch clip is removed.
The latch clip may be used on certain fuel line/
fuel rail connection, or to join fuel lines together.
18. Pry up on latch clip with a screwdriver (3).
19. Slide latch clip toward fuel rail while lifting with
screwdriver.
20. Insert special fuel line removal tool (Snap-On
number FIH 9055-1 or equivalent) into fuel line
(1). Use tool to release locking fingers in end of
line.
21. With special tool still inserted, pull fuel line from
fuel rail.
22. After disconnection, locking fingers will remain
within quick-connect fitting at end of fuel line.
23. Disconnect quick-connect fitting from fuel system
component being serviced.

24.Latch Clips — Type 2:Depending on vehicle
model and engine, 2 different types of safety latch
clips are used. Type-1 is tethered to fuel line and
type-2 is not. A special tool will be necessary to
disconnect fuel line after latch clip is removed.
The latch clip may be used on certain fuel line/
fuel rail connection, or to join fuel lines together.
25. Type 2: Separate and unlatch small arms (1) on
end of clip and swing away from fuel line.
26. Slide latch clip toward fuel rail while lifting with
screwdriver.
27. Insert special fuel line removal tool (Snap-On
number FIH 9055-1 or equivalent) into fuel line
(1). Use tool to release locking fingers in end of
line.
28. With special tool still inserted, pull fuel line from
fuel rail.
29. After disconnection, locking fingers will remain
within quick-connect fitting at end of fuel line.
30. Disconnect quick-connect fitting from fuel system
component being serviced.
CONNECTING
1. Inspect quick-connect fitting body and fuel system component for damage. Replace as necessary.
2. Prior to connecting quick-connect fitting to component being serviced, check condition of fitting and component.
Clean parts with a lint-free cloth. Lubricate with clean engine oil.
3. Insert quick-connect fitting intofuel tube or fuel system component until built-on stop on fuel tube or component
rests against back of fitting.
4. Continue pushing until a click is felt.
5. Single-tab type fitting: Push new tab down until it locks into place in quick-connect fitting.
6. Verify a locked condition by firmly pulling on fuel tube and fitting (15-30 lbs.).
7. Latch Clip Equipped: Install latch clip (snaps into position).If latch clip will not fit, this indicates fuel line is
not properly installed to fuel rail (or other fuel line). Recheck fuel lineconnection.
8. Connect negative cable to battery.
9. Start engine and check for leaks.

MODULE-FUEL PUMP
DESCRIPTION
The electric fuel pump is located inside of the fuel pump module. A 12 volt, permanent magnet, electric motor pow-
ers the fuel pump. The electric fuel pump is not a separate, serviceable component.
OPERATION
Voltage to operate the electric pump is supplied through the fuel pump relay.
Fuel is drawn in through a filter at the bottom of the module and pushed through the electric motor gearset to the
pump outlet.
Check Valve Operation:The bottom section of the fuel pump module contains a one-way check valve toprevent
fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational.
It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled
down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line
between the check valve and fuel injectors.Fuel pressure that has dropped to 0 psi on a cooled down vehicle
(engine off) is a normal condition.
The electric fuel pump is not a separate, serviceable component.

MODULE - FUEL PUMP
DESCRIPTION
The fuel pump module assembly is located on the top of the fuel tank. The complete assembly contains the fol-
lowing components:
A combination fuel filter/fuel pressure regulator
A separate fuel pick-up, or inlet filter
An electric fuel pump
Alockringtoretainpumpmoduletotank
A soft gasket between tank flange and module
A fuel gauge sending unit (fuel level sensor)
Fuel line connection
The fuel gauge sending unit may be serviced separately. If the electrical fuel pump, primary inlet filter, fuel filter or
fuel pressure regulator require service, the fuel pump module must be replaced.
OPERATION
Refer to Fuel Pump, Inlet Filter, Fuel Filter / Fuel Pressure Regulator andFuel Gauge Sending Unit.
REMOVAL
WARNING: The fuel system may be under a constant pressure (even with the engine off). Before servicing
the fuel pump module, the fuel system pressure must be released.
1. Drain and remove fuel tank. Refer to Fuel Tank
Removal/Installation.
2. Note rotational position of module before attempt-
ing removal. An indexing arrow is located on top of
module for this purpose.
3. Position Special Tool 9340 (3) into notches on out-
side edge of lockring (5).
4. Install 1/2 inch drive breaker bar (1) to tool 9340
(3).
5. Rotate breaker bar counter-clockwise to remove
lockring (5).
6. Remove lockring. The module will spring up slightly
when lockring is removed.
7. Remove module from fuel tank. Be careful not to
bend float arm while removing.

RAIL - FUEL
DESCRIPTION
The fuel injector rail is used to mount the fuel injectors to the engine.
OPERATION
High pressure from the fuel pump is routed to the fuel rail. The fuel rail then supplies the necessary fuel to each
individual fuel injector.
A quick-connect fitting with a safety latch clip is used to attach the fuel linetothefuelrail.
The fuel rail is not repairable.
CAUTION: The left and right sections of the fuel rail are connected with either a flexible connecting hose, or
joints. Do not attempt to separate the rail halves at these connecting hoseor joints. Due to the design of
the connecting hose or joint, it does not use any clamps. Never attempt to install a clamping device of any
kind to the hose or joint. When removing the fuel rail assembly for any reason, be careful not to bend or
kink the connecting hose or joint.
REMOVAL
