Unless you want to lug a generator to the back if the staging lanes, you can use a 12 volt utility pump from Harbor Freight in your ice chest style "chiller". Comes with garden hose fittings on both sides. Comes with alligator clips on the wires, so you can just clamp onto a 12 volt battery to run it. Some guys build a sheet metal box for a small battery, and mount it to the side of the ice chest. Most use clear hose to see the water flowing. Push on hose fittings are at Lowes Home Centers and Ace Hardware. Cheap and easy to build. I found my plastic ice chest, which has wheels on one end & a raise-up handle on the other, at Dollar General.
