When the OCS is positioned as shown below, the internal screen is in the incorrect position, with the cone of the screen at the bottom.



Since we can't see inside the OCS for the improper orientation of the screen, we use the external location of objects to verify the improper orientation.

The tube should be located at the top of the OCS. The clamp should be located at the bottom of the OCS. These objects are inverted in the photo, which shows the improper orientation. The big loop in the tube also indicates the internal screen is improperly oriented.

The tube has a big loop because it must travel to the bottom of the OCS. The problem is not caused by a pinch in the tube. The big loop in the tube is merely an external indication that the internal screen is upside down, which will promote the collection of more liquid fuel in the down tube.
