Warning:
- Gasoline is extremely flammable, therefore, when working with fuel system components, the use of fire, sparking devices, open fire-hazardous lighting devices and smoking are prohibited. Avoid sparking when handling wires and electrical devices.
- Prevent dirt from entering the fuel system.
- Before servicing fuel system components, relieve fuel system pressure. Disconnect the connector from the fuel pump. Start the engine and wait until it stops due to the fuel lines and fuel rail running out. To finally reduce the pressure in the fuel system, turn the engine crankshaft with the starter for 5 seconds.

Removal
Disconnect the connector from the engine air temperature sensor located on the air intake tube (1).
Disconnect the resonator hose from the air intake tube (1).
Remove the air intake tube (1) and the air filter housing cover (2) as an assembly.
Remove the hollow bolts and disconnect the fuel lines from the fuel rail.
Disconnect the connectors from the fuel injectors.
Disconnect the hose from the fuel pressure regulator.
Remove the fuel rail from the intake manifold.
Remove the spring clips (1) and remove the fuel injectors from the fuel rail.
Warning: The position of the fuel injector retaining spring clips may prevent the injectors from being properly installed into the fuel rail, so align the position of the spring clips before installing the injectors.
