- Remove the fuel filler cap from the fuel filler tube.

- Install the shaft piece - 1 - for the (VAS 5190 ) in the fuel tank filler tube.





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





- Empty the fuel tank as much as possible via the fuel filler tube.

- Carefully pull out the suction hose.

• When no more fuel is being siphoned, the fuel tank is emptied just enough to open the fuel delivery unit safely. The tank may be removed while containing the remaining fuel.

• How to drain fuel tank completely, refer to => [ Less Than 3/4 Full ].
