Special tools, testers and auxiliary items required

• Fuel Extracting Device (VAS 5190)

Procedure

Observe safety precautions. Refer to => [ Fuel System ] Fuel System.

Observe rules for cleanliness. Refer to => [ Clean Working Conditions ] Fuel Supply System.


Secure the fuel extracting device (VAS 5190) ground (GND) wire to a bare area of the chassis.

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






- Using insulating tape, apply a mark - arrow - on hose at length - a - = 1,370 mm from end of suction hose.

- Remove fuel filler cap from fuel filler tube.

- Install the adapter - 1 - for the (VAS 5190) on the fuel tank filler tube.






- Slide suction hose as far into fuel tank until the mark applied earlier - arrow - stands on shaft piece.

• If using a fuel siphoning device without shaft piece, proceed principally in the same manner.

• In this case, apply a mark - arrow - using insulating tape on hose at length - a - = 1,305 mm from end of suction hose. The suction hose is inserted correctly when the marking applied earlier aligns with the lip of the fuel filler neck.






• If the hose can only be inserted with difficulty, coat it thinly with engine oil. Never use lubricants containing silicon.

- Drain fuel tank through fuel filler tube.

- Carefully pull out the suction hose.
