Hey KW_Counter- good for you guys... Ihave been using an old fuel tank with a short piece of brass tubing in it connected to the vent line to catch the overflow. I can on a good day, save an entire tank of fuel by using it. It is also simple to pump out when it starts to fill up, and Ireconnect the two lines (vent to carb) on it to keep from pulling in moisture at the in between times. It is no effort to use, and I figure that it saves me about a gallon of fuel every year. Edit - I thought about doing it because Ihave to fix my own grass, as my runway is mine. At first I just did it to save bald spots in the pits, then Ifound out how much fuel I was losing....
