4100 GPH is a lot of flow and way more then you need. For that much flow you really want 1.5” tubing. I doubt you overflow will be able to handle 4100 gph. It is also very possible your sump will not either. It costs a lot in electricity to pump that much water up 6’ or so with no real benefit. Like uncle said 1800 GPH is plenty.
