Pinch the retainer of the fuel tube connector, and then pull the fuel tube connector off of the fuel pipe.
Note
Check for foreign matter on the fuel tube around the fuel tube connector. Clean it if necessary. Foreign matter can affect the ability of the O-ring to seal the fuel tube connector and fuel pipe.
Do not use any tools to separate the fuel tube connector and fuel pipe.
Do not forcibly bend, kink or twist the nylon tube.
Keep the fuel tube connector and fuel pipe free from foreign matter.
If the fuel tube connector and fuel pipe are stuck, push and pull to release them.
Cover the fuel tube connector and fuel pipe with plastic bags to prevent damage and contamination.
Disconnect the fuel tube sub-assembly from the fuel hose clamp.

Disengage the clamp to disconnect the wire harness.
REMOVE FUEL DELIVERY PIPE
Remove the 2 bolts, and then remove the fuel delivery pipe together with the 4 fuel injector assemblies.
Note
Be careful not to drop the fuel injector assemblies when removing the fuel delivery pipe.
Remove the 2 fuel delivery spacers from the cylinder head.
Remove the 4 injector vibration insulators from the cylinder head.
REMOVE FUEL INJECTOR ASSEMBLY
Pull the 4 fuel injector assemblies out of the fuel delivery pipe.
Remove the O-ring from each fuel injector assembly.
For reinstallation, attach a tag or label to each fuel injector shaft.
