Work procedure

CAUTION: Observe procedures for disconnecting battery Electrical Equipment -.

- Push cover over battery toward right - arrow 1 - and remove it upward - arrow 2 -.







- With ignition switched off, disconnect Battery Ground (GND) strap - arrow -.

CAUTION: Secure Ground (GND) wire of fuel extraction unit VAS 5190 to a bare area of the chassis.







- Pull cone piece -2- from shaft end -1- of fuel extraction unit VAS 5190.
- Using insulating tape, apply a mark - arrow - on hose at length - a - = 1,865 mm from end of suction hose.







- Remove fuel filler cap from fuel filler tube.
- Screw shaft end -1- of fuel extraction unit VAS 5190 on to fuel filler tube of fuel tank.
- Push the suction hose as far into fuel tank until the mark applied earlier - arrow - is positioned on shaft end.







NOTE:
- If using a siphoning device without shaft end, proceed basically in the same manner.
- In this case, apply a mark - arrow - using insulating tape on hose at length - a - = 1,800 mm from end of suction hose. The suction hose is inserted correctly when the marking applied earlier stands opposite the lip of fuel filler tube.
- 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 as much as possible.
- Carefully pull out suction hose.
