I want to thank you guys for all your comments. It's funny how many people will argue over a few ounces of fuel. Honestly I'll bet you have spilled more gas on the ground, removing you tank or that leaky carb that you haven't fix yet, then what will be left in the tank using this set up. This video was about making it easy to get your tank off without having to drain it. And for all you guys worried about running out of gas, fill your tank, gas is cheap, and you can get your tank off easy now if it's half full.
P.S. For you guys with 350s, it works for those too. I have two of them. The routing is a little different but you get the idea.
