(3) Install hoses to filter. Tighten clamps to 1 N*m
(10 in. lbs.) torque.
(4) Lower vehicle.

(6) Start engine a n d check for leaks.
FUEL FILTER—5.9L GAS ENGINE
For diesel engines, refer to Fuel/Water Separator
Filter in the Diesel Fuel Injection—Service Proce­
dures section of this group.
The fuel filter and fuel pressure regulator (Fig. 21)
are one non-repairable component. For service, refer
to Fuel Filter/Fuel Pressure Regulator. This can be
found in the Multi-Port Fuel Injection (MPI)—Com­
ponent Removal/Installation section of this group.

Inspect all hose connections such as clamps, cou­
plings and fittings to make sure they are secure and
leaks are not present. The component should be re­
placed immediately if there is any evidence of degra­
dation t h a t could result in failure.
Avoid contact of any fuel tubes/hoses with other ve­
hicle components t h a t could cause abrasions or scuff­
ing. Be sure t h a t the plastic fuel tubes are properly
routed to prevent pinching and to avoid heat sources.
C A U T I O N : The tubes/hoses used o n 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 tubes/hoses, only tubes/hoses
marked E F M / E F I may be used.
C A U T I O N : The hose clamps used o n fuel injected
vehicles are of a special rolled edge construction 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 h o s e s and cause high pressure fuel
leaks.
Use new original equipment type hose clamps.
Tighten hose clamps to 1 N*m (10 in. lbs.) torque.
QUICK-CONNECT FITTINGS
Also refer to t h e previous Fuel Tubes/Lines/Hoses
and Clamps.
Two different types of Quick-Connect fittings are
used at several fuel system connections. One type of
fitting will be referred to as a Tab Type Fitting. The
other will be referred to as a Plastic Ring Type fit­
ting.
C A U T I O N : Quick-connect fittings are not serviced
separately. Do not attempt to repair damaged quick-
connect fittings or fuel tubes. Replace the complete
fuel tube/quick-connect fitting assembly.
TAB TYPE FITTING
This fitting is equipped with a retainer t a b (Figs.
22 or 23) t h a t must be released prior to disconnecting
the fitting from the fuel tube. This type of fitting can
be disassembled either manually or with a straight
blade screwdriver.
