CAUTION!
Fuel system is under pressure! Always follow safety measures before opening the system. Refer to => [ Safety Precautions ] Safety Precautions.

- Place a cloth around the union nut - 3 - and carefully loosen it to lower the fuel pressure.

- Remove the distribution piece from the intake manifold - arrows - and remove the hose - 4 -.

- Move the distribution piece with the supply line still connected to the side.

- Remove the bleeder hose - arrow - from intake manifold.





- Remove Evaporative Emission (EVAP) canister purge regulator valve (N80) - 1 - down from bracket.
