- As there is retained pressure in the fuel pipe line, prevent it from splashing inside the engine compartment.




3. REMOVE DELIVERY PIPE AND INJECTORS

NOTE: Be careful not to drop the injectors when removing the delivery pipe.

a. Disconnect the 4 injector connectors from injector.
b. Remove the 3 bolts and delivery pipe together with the 4 injectors and fuel pipe.
