•
Place the bolts on module cover and tighten the bolts gradually in star pattern sequence to
apply equal compression on gasket. It is shown in figure as below. Bolt Tightening Torque:
3~4 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。
5. Pressure Regulator Assembly Replacement:
•
Remove the regulator retainer from module.
•
Apply gradual pull force on retainer to avoid any personal injury due to spring action of
retainer.
•
Take out the pressure regulator assembly from module.
•
Do not hit/ damage on the regulator dome and crimping portion.
•
Lubricate the O-rings in new pressure regulator assembly with recommended lubrication
oils as mentioned in Table no: 3. Lubrication oil is applied only for ease of regulator
assembly.
•
Make sure that 2 O-rings (one is bigger diameter the other is smaller diameter) are
assembled in pressure regulator.
•
Place the pressure regulator on module at regulator pod. Push the regulator gently in the
pod.
•
Do not hit/ damage on the regulator dome and crimping portion. This will disturb the
pressure setting.
•
Assemble the retainer on the regulator pod
•
Replace the gasket, module with new gasket provided in the kit.
6. Fuel Pressure Relief Procedure:
ENGINE MANAGEMENT SYSTEM
Mounting Bolts – Star Tightening Pattern
NOTE
This work must not be done when engine
is hot. If done so, it may cause adverse effect to
catalyst (if equipped)
