  1. Open drain screw (A) by 3/4 of a turn. Retighten the screw as soon as water and sediment deposits have drained out.

  2. Open drain screw (B) by 3/4 of a turn. Retighten the screw as soon as water and sediment deposits have drained out.

  3. Turn ignition switch to the right to the first switch position so that the fuel transfer pump is operating. Keep the pump running for approx. 40 seconds.
