Using the Fuel Pump

Special tools, testers and auxiliary items required

• Fuel Extracting Adapter (VAS 5190/3)

• Test Instrument Adapter/DSO (5-pin) (VAS 5565)

• Remote Control (V.A.G 1348/3A)

CAUTION!
• Fuel supply line is under pressure! Wear protective goggles and protective clothing to prevent injuries and contact with skin. Before loosening hose connection wrap a cloth around the connection. Loosen the connection carefully to release the pressure.

• Connect the (VAS 5190) ground wire with the vehicle ground strap.

- Disconnect fuel supply line - arrow -. To do so, press in the securing ring.





- Seal the pipes so that the fuel system is not contaminated by dirt etc.

- Connect the (VAS 5190) with the (VAS 5190/3) to the fuel supply line.





- Remove the rear seat bench.

- Remove the cover from the fuel delivery unit.





- Disconnect the connector - arrow -.





- Connect the (VAS 5565) to the connector on the cover and on the fuel delivery unit.





- Connect the (V.A.G 1348/3A) to the (VAS 5565) and to the battery positive (+).

• This step allows the fuel pump to run when the engine is not running.

- Remove fuel filler cap from fuel filler tube.

- Operate the (V.A.G 1348/3A) and the shut off valve on the (VAS 5190) until the fuel tank is empty.

CAUTION!
Do not run the fuel pump dry.

Through the Fuel Tank Filler Tube

• Vehicles with engine codes BGQ and CBUA have a bayonet connection and require a corresponding adapter.

• If the adapter is not available, the threaded section on the (VAS 5190) must be held in place.

CAUTION!
Secure the (VAS 5190) ground wire to a bare area on the chassis.

- Remove the cone piece - 2 - from the shaft piece - 1 - on the (VAS 5190).





- Using insulating tape, apply a mark - arrow - on the hose at a length - a - = 1,500 mm from the end of the suction hose.

- Remove the fuel filler cap from fuel filler tube.

- Install the shaft piece - 1 - from the (VAS 5190) into the fuel tank filler tube.





- Insert the suction hose into the fuel tank until the mark made earlier - arrow - aligns with the shaft piece and extract the fuel. Refer to the (VAS 5190) operating instructions.

• A pressure point can be sensed after approximately 120 cm. Check valve in fuel tank must be pushed open. Pull out hose slightly and slide it in using a light jerk.

• Fuel tank is drained almost completely.

• Remove the hose the same way.
