I know I know. It just seems so whatever. I fill up my two 5 gal steel tanks http://www.hardwareandtools.com/invt/u440677 and throw them in the back of the pickup. Takes a couple minutes at the pump. Than I get to the hangar and throw those tanks in the hangar, my wife does it, figure that one. Than when I need the fuel, which isn't all that much concidering the RV. In which time I put the snout on the steel tank and lift it into the plastic jug and let it balance itself there until it is emptied. Than I look down in the jug, I have a white one, and check for water and junk. Than I put the ladder to the wing, have to do that anyway. Climb up the ladder with the jug, oh my god there is a job, shhhhh. I take the cap off, I put the tube in the hole, oh my, that's got to be a hard one, and than lift the jug, 3 minutes or less the fuel is in.
One thing, I never fill the tanks on the kitfox unless I take it out of town. That means I fly with 5 to 10 gallons tops for local flights. Also means that when I fly I have fresh fuel. If it's been a long time between flight, ya right not for me, than I just dump the steel tanks into my pickup and go get some fresh. If I have old fuel in the wing tanks, not likely, than either adding fresh will rejuvinate the old or I just stick a hose in the tank and empty it out, real quick and easy, than emty that into the pick up. With 5 gal in a 13 gal tank, you can usually fold the wing with no problems.
