Where are you guys putting the sensor for the 3155? It has to go in the pump compartment but the only place it can go is right under and to the left of the stock float. It's tricky to get the outside magnet on due to limited space. I can't get my hand back there that low.

Mine is in the pump side, but towards the front. Getting the outer magnet on was bit tricky because it's a tight fit. There isn't much spare space between the sump and stand.

You might be able to place it on the front of the sump (between the sump and door). I believe there's enough space there.
