Would this restricted pump outlet be more efficient next to the outlet of the pump, or after the hose near the deck?

location makes little difference from the perspective of the restrictor, solong as it has clean flow inbound...  however, the longer the tube the more loss in the tube leading to the restrictor.

as a side note, every restrictor using club I am aware of requires them to be where they can be measured, e.g. at the deck.
