Fuel Module Orientation: Fuel module bolts not
symmetrical and can be mounted
only in the intended direction. Regulator side
should be facing the Fuel Tank rear
side.
Make sure that the fuel tank surface at module
mounting area is clean and free of
surface defects.
Place the bolts on module cover and tighten
the bolts gradually in star pattern
sequence to apply equal compression on
gasket. It is shown as below.
Bolt Tightening Torque: 4.4 Nm.
Fuel module is installed with special bolts (step
bolts). Use designated bolts only.
Follow the tightening torque and tightening
sequence instruction. Over torque and
miss-sequence can cause unequal
compression of gasket and leakage.
Install the fuel tank to vehicle.
Connect for fuel hoses with suitable hose
clamps.
Connect fuel module coupler
Follow “Fuel Leakage Check Procedure’ to
check any leakage before the engine is
started.
Fuel Pressure Relief Procedure:
Caution: This work must not be done when
engine is hot. If done so, it may cause
adverse effect to catalyst (if equipped)
After making sure that engine is cold, relieve
fuel pressure as follows.
Place vehicle gear in ‘Neutra
l’.
Disconnect fuel module electrical coupler
from vehicle harness.
Start engine and run till it stops due to lack
of fuel. Repeat ignition key ON and OFF
for 2 ~ 3 times of about 3 seconds each time to
relieve fuel pressure in lines. Fuel
Connections are now safe for servicing.
Upon the completion of servicing, Connect
Fuel Module Connector to Vehicle Harness
