INSTALLATION
1. INSTALL FUEL PRESSURE PULSATION DAMPER ASSEMBLY
a. Install 4 new gaskets and 2 pulsation dampers together with the No. 2 fuel pipe to the delivery pipe.
b. Using SST, tighten the 2 pulsation dampers.
Torque:
33 N.m(337 kgf.cm, 24 ft.lbf) for use with SST
39 N.m (398 kgf.cm, 29 ft.lbf) for use without SST
HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.81 in.)
- Make sure SST and a wrench are connected in a straight line.
c. Install the bolt to the No. 2 fuel pipe clamp.
Torque: 5.0 N.m(51 kgf.cm, 44 in.lbf)
d. Using SST, install the fuel pipe.
SST 09023-38401
Torque:
28 N.(286 kgf.cm, 21 ft.lbf) for use with SST
35 N.m (357 kgf.cm, 26 ft.lbf) for use without SST
HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.81 in.)
- Make sure SST and a wrench are connected in a straight line.
2. INSTALL INTAKE AIR CONNECTOR PIPE
3. INSTALL NO. 1 AIR CLEANER INLET
4. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
5. PERFORM INITIALIZATION
a. Perform initialization.
NOTE: Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.
