the tip about not pulling the plug out all the way is a bit late for me, I set up a square grape juice container just like you showed and it worked great other than the pressure was a bit much and I did get some splashing on other things. it did end up having about 5 gallons of 2 year old fuel in it (saved it for the lawnmowers now), but now its all filled up with fresh fuel and running like a champ.
