I guess I don't understand what you are trying to accomplish here. I drain my generator after I'm done using it. It has a 5 gallon tank with a petcock. I close the petcock, run the carb dry (some have a drain in the bottom of the bowl), disconnect the fuel line from the petcock, attach a hose to the petcock and drain into a gas can. Use the gas in a lawn mower or whatever or pour it into a car. Reconnect the gas line and you are good to go, gas it up next time you need it and it should start right up. The draining process takes about 5 to 10 minutes, at one point, my generator started right up after being stored like this for 8 years. ( you need to store in a dry place)
As said before av gas has lead in it and cause problems like fouling plugs and so on, not to mention the exhaust is bad for you.
