I use one that looks just like this….http://www.walmart.com/ip/Pennzoil-Siphon-Pump/16795103. It uses 1/4 tubing, so it works great. I remove the fuel line running to the carb on top of the fuel tank, and put one end of the siphon on it. The other end goes into my race fuel jug. Pinch the line before you squeeze the bulb, and when you release the bulb release the line, and it should start siphoning. Basically you are using your existing fuel pickup hose inside your tank, so it empties your tank almost completely.
