I am installing a Hanger 9 Fuel Dot in my latest project. This is the first time I have used a fuel dot. I am under the impression that it is installed as a third fuel line directly into the tank. However, Hanger 9 supplies a T connection in the package with the fuel dot which seems to infer that the dot is installed using the normal two fuel line hookup on the line from the tank to the engine. What confuses me with this set-up is that if I installed it that way, then what will prevent some of the fuel from going directly toward the engine when I am fueling the plane. Could someone who has experience with these fuel dots please enlighten me. Thanks.
