Too Hot? Keep cool at home, car, outside with the Back Cooler

Step 2 Ice Chest set up

Drill two holes for the 3/8" tubes and one for the wires. Size your drill bit so they are snug. The position must be near the top of the chest. The lines will tangle less if it's near the pivot of the handle, it depends on how your ice chest is made. Think twice, drill once

Bilge pump: It will work in any position so I didn't mount it. Most pumps have a mounting bracket, you can try gluing it to the bottom or side of the chest. It's easier to clean the pump and chest if it's not mounted. My pump has a 3/4" OD, find an adapter to fit yours. The seal does not have to be water tight on the bilge pump.

Connect the wires to the bilge pump wires outside the ice chest. The Rule model pumps are not polarized, but if yours is connect it correctly! If you want to put a switch in line, go for it. You can also wire it to your car's fuse box with a disconnect.

The supply and return tubes are interchangeable. Make the lines long enough to reposition around ice bottles if needed.

Use the nylon ties on the inside to keep the tubes and wires from being pulled out. Not too tight!
