You can use braided fuel line hose from any auto parts store or big box hardware store, but Mill Rat is correct that the beer lines need to be food grade 3/16" ID, and that's harder to find. I have to buy it online from homebrew shops. If you have a local homebrew shop they'll probably have it. Don't let them sell you 1/4" ID, you'll have foam problems from day one.
It's always time for a beer
