Fuel Delivery and Air Induction: Service and Repair

Fuel Supply Servicing

• Fuel hoses at the engine may only be secured with spring type clamps appropriate for the model type.

• Spring type clip pliers (VAS 6499) or hose clip pliers (VAS 6362) are recommended for installing spring clamps.

• If the fuel delivery unit was replaced, adapt the Engine Control Module (ECM) to the fuel pump. Refer to "Guided Functions" in the vehicle diagnostic tester.
