I fill from the fill tube.... They have 3 tubes, vent (pink), carb (blue), and fill (green).
you pinch the carb line with hemostats when you fill if that is your set-up.
Pull the muffler line, too, so you can see when the tank is full or you'll fill the muffler, too.
To add to what Charlie P. suggested.
I also added a piece of heat shrink to the jaws of the hemostats to prevent them from puncturing my fuel line. (a piece of electrical tape would probably work)
