- Slide the suction hose into the fuel tank until the mark applied earlier - arrow - aligns with the shaft piece.
• Suction hose must not be slid in further, since otherwise the inner components may be damaged.
- Drain the fuel tank as much as possible.
- Carefully pull out the suction hose.
• When fuel is no longer extracted, the fuel tank is emptied just enough to open the flange of the fuel delivery unit safely.
• If the fuel tank must be drained completely, refer to Less Than 3/4 Full.
