The Feifel air filters, at the top rear of the Tiger, were attached to the real vehicle by only 4 metal strips. On a scale model, this results in a weak attachment for these parts. But on the other hand, the air hoses in the model are much stronger than the real ones, and they can provide a solid seating for the model's Feifel filters.
Ensure that the filters sit correctly on the hull rear, and then apply the air tubes to support them firmly. The filters should be parallel to the rear wall; they should not be vertical.
