The fuel filter/pressure regulator is located on the underbody at the forward
edge of the left-side of the fuel tank.
Position on a hoist.
Disconnect the negative battery cable.
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.
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.
Raise the vehicle to a comfortable working height.
Remove the 2 fuel filter/pressure regulator bracket screws (10 mm hex).
Unlatch the fuel line bundle retaining clip on the left-side of the fuel
tank.
Notice
Take care not to damage the retaining clip when opening it. The fuel lines must
be retained in this clip, and if damaged, the fuel tank assembly must be replaced
since the retaining clip is not serviced separately.
Disconnect the evaporative emission (EVAP) purge line at the 90 degree
quick connect.
Caution
Whenever fuel line fittings are loosened or removed, wrap a shop cloth around
the fitting and have an approved container available to collect any fuel.
Slide the outlet of the filter/regulator out of the support on
the fuel tank bracket and remove the fuel feed line at the 90 degree quick
connect.
Pivot the filter/regulator down while moving the leg of mounting bracket
out from under the chassis brake lines.
Important
It is not necessary to remove the filter/regulator from the bracket. Both items
are serviced as an assembly.
Disconnect the fuel feed and return lines at their quick connect fittings on
the filter/regulator.
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.
Install the 3 new fuel line retainers into the female portion of
the quick connect fuel line fittings.
Important
Lubricate the male ends of the filter/regulator with clean engine oil to ease
installation and snap closed.
Install the fuel feed and fuel return lines onto the filter/regulator.
Place the fuel feed, return, and EVAP purge lines into the fuel tank retainer
clip.
Slide the leg of the filter/regulator bracket under the chassis brake
lines and pivot the filter/regulator up.
Install the 90 degree fuel feed line quick connect on the filter/regulator
outlet.
Connect the 90 degree EVAP purge line quick connect to the purge
line.
Place the fuel feed outlet pipe of the filter/regulator into the clip on the
fuel tank bracket.
Ensure the chassis fuel feed and purge lines are routed on top of the emergency
brake cable. The emergency brake cable must be secured firmly to the underbody to
support the fuel and purge lines.
Install 2 filter/regulator bracket attachment screws, 10 mm hex.
Tighten
Tighten the fuel filter/pressure regulator-to-frame rail to 8 N·m
(17 lb in).
Connect the negative battery cable.
Tighten
Tighten the battery terminal bolts to 17 N·m (13 lb ft).
Energize the fuel pump and check for leaks at the filter/regulator.
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.
