| *1 | O-ring |
| *2 | Injector Vibration Insulator |
Apply a light coat of gasoline or spindle oil to new injector vibration insulators and new O-rings, and then install one to each fuel injector assembly.
Apply a light coat of gasoline or spindle oil where the fuel delivery pipe sub-assembly contacts each O-ring.
While turning the fuel injector assembly left and right, install it to the fuel delivery pipe sub-assembly.
- NOTICE:
- ·
Do not damage the fuel injector assembly or O-ring.
·Make sure that the O-ring is not twisted or moved out of place when installing the fuel injector assembly.
·After installing each fuel injector assembly, check that it turns smoothly. If not, replace the O-ring with a new one.
- HINT:
-
Use the same procedure to install the other fuel injector assemblies.

6.CONNECT FUEL TUBE SUB-ASSEMBLY
- NOTICE:
-
Check that there is no damage or foreign matter on the connecting parts of the fuel lines.
| *a | Retainer |
| *b | O-ring |
| *c | Nylon Tube |
| *d | Fuel Tube Connector |
| *e | Fuel Pipe |
Connect the fuel tube sub-assembly to the fuel delivery pipe sub-assembly.
Align the fuel tube connector with the fuel pipe, and push them together until the fuel tube connector makes a "click" sound. If it is difficult to push the fuel pipe into the fuel tube connector, apply a small amount of clean engine oil to the tip of the fuel pipe and reinsert it.
After connecting the fuel lines, check that the fuel pipe and fuel tube connector are securely connected by pulling on them.
Engage the 2 claws to install a new No. 2 fuel pipe clamp.
