Portable 12V Air Conditioner --Cheap and easy!

Step 5 Attach the Bilge Pump

The ArcticAir unit just leaves their bilge pump just dangling from the hose, but we wanted it to be more secure. The pump has a twist-off base, so we twisted it off and Gorilla Glued it to the bottom of the cooler. Make sure that it is angled so that you can easily run a hose from the pump output to the heater core input. We attached the base directly to the bottom of the cooler, which works fine, but we probably should have put some spacers in to increase water flow underneath. Also, the picture just shows where it goes. We haven't attached that hose yet, so ignore it.
