haven't played with a pee wee in ages so don't remember run time but it's probably under two minutes.
either nipple can be used for filling and when fuel comes out of the other it's full. oh, and if the nipples are on the tank itself and not cast as part of the backplate then you have a widow and not a pee wee...

you can add a tank but the best method requires that you cut a big hole in the tank...the link i gave you before will have a lot more info on doing this plus some photos. do a search there or just ask, they're usually pretty nice guys if they've had their coffee.
