There is an approx 12" long tube that connects the pickup assy to the oil pump port in the block. It has a compression fitting at each end which could conceivably come loose. Even if the floating pickup has fallen off, the end of the pickup assy will still be be submerged.

You could in a few minutes remove the the oil sender union out of the block and crank a bit to see what happens.

The floating pickup was to gather clean oil off the top and let chunks -if any-settle.

Partial flow filters work on the same principle as swimming pool filters: they were to filter out the slow accumulation of dust, wear particles and sludge to keep the oil clear. Engines are not supposed to be throwing chunks off into the oil any more than kids are supposed to throw dirtballs into the swimming pool.
