Don't follow the video by installing the pump connector on the pump discharge first or you may not get full tightness when the spray arm water supply tube (nut) is both screwed on and oriented towards the back for the upper spray arm, due to the nature of the coarse threads. Instead, "index" the nut on the connector so that it's both tight on the connector and the upper discharge nipple is pointed back. Then reinstall the pump on the connector.and don't forget to put the clamp back on first too.
