The fuel feed line and the evaporative emission (EVAP) canister purge line are
routed together on the underbody up to the fuel rail. The 2 lines are serviced as
an assembly.
Removal Procedure
- Position the vehicle on the hoist
Caution: Fuel supply lines will remain pressurized for long periods of time after the
engine is shutdown. This pressure must be relieved before servicing the fuel system.
- Relieve the pressure in the fuel system at the fuel pressure
test port. Refer to
Fuel Pressure Relief
.
- Remove the retaining screw, 10 mm hex, at the fuel line clip
to the intake manifold brace.
Notice: To prevent fuel from draining out of the fuel rail, install a soft plastic or
vinyl cap over the fuel rail connection.
- Disconnect the fuel feed line at the fuel rail and the EVAP canister
purge line at the purge solenoid, both are quick connects.
Caution: Ensure that the vehicle is properly supported and squarely positioned.
To help avoid personal injury when a vehicle is on a hoist, provide additional support
for the vehicle on the opposite end from which the components are being removed.
Important: The purge solenoid connection may be more accessible from under vehicle.
- Raise the vehicle to a comfortable working height.
- Disconnect the 90 degree fuel feed line quick connect at the outlet
of the fuel filter/pressure regulator.
- Disconnect the 90 degree EVAP canister purge line quick connect
at the front edge of the fuel tank.
- Remove the 4 attachment screws, 10 mm hex, and remove
the fuel/brake line shield on the underbody.
- Remove all 6 attachment nuts, 10 mm hex, securing the
fuel/purge line bundle retainer clips to the underbody and remove the clips from
the brake lines.
- Open the retainer clip at the left-hand body side rail and remove the
fuel and purge line.
- Remove the fuel/purge line bundle from the vehicle.
Installation Procedure
- Load the fuel/purge line bundle, with retaining clips attached, to the underbody
from under the vehicle.
- Compare the position of the retaining clips on the lines to the attachment
stud location on the underbody and adjust the position of the clips as necessary.
Notice: Refer to Fastener Notice in the Preface section.
- Install the retaining clips to the brake lines and attachment studs with nuts,
10 mm hex.
Tighten
Tighten the brake line retaining clip to 2.5 N·m (22 lb in).
- Install the fuel and brake line shield to the underbody with (4) attachment
screws, 10 mm hex.
Tighten
Tighten the fuel line shield-to-underbody to 12 N·m (9 lb ft).
Notice: Replace plastic fuel line retainers whenever the fuel supply or return line
is disconnected at the fuel rail. Install the new retainer into the female cavity
of the connection. Care must be taken to ensure that the locking tab is centered in
the window of the female cavity. Firmly press the female connection onto the male
end until a click is heard, then pull back to confirm engagement. Pinched, kinked,
or damaged fuel lines must be replaced.
- Connect the fuel supply line to the filter/regulator outlet and
the chassis purge line to the fuel tank purge line.
- Connect the chassis purge line to the EVAP canister purge solenoid.
- Install the forward fuel line retaining clip to the intake manifold brace with
an attachment screw, 10 mm hex.
Tighten
Tighten the fuel line retainer clip to 4 N·m (35 lb in).
- Connect the fuel feed line to the fuel rail.
- Energize the fuel pump and check all connections for leaks.
- Perform the Service Bay Diagnostic Test for the evaporative emission
system using the scan tool. This test will verify the integrity of the vapor handling
areas of the fuel system. Refer to Service Stall System (SSS) user guide.
