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.

Most of us install fuel dots on a 3rd line. This is easily done on fuel tanks with brass tubes. Bend the fuel dot brass tubing to the bottom of the tank so you can suck fuel out after flying.

If you use one of the tanks with fixed plastic nipples, you won't be able to de-fuel unless you invert the plane or stand it on its nose. With a low wing plane, you can de-fuel with the plane inverted in the cradle after you take the wing off.

To use a dot in the normal feed line with the T in the line, you'll need to clamp off the line to the carb with hemostats so you don't flood your engine during fueling.

Glow or gas, the "T" goes between the carb and tank. The third leg of the "T" goes to the out side for fueling. The fuel dot plugs the filling line.

Thanks alot for the help fellows. It is pretty much what I thought. I was a little confused however, because of the dot being supplied with a T connector. Have a good one.

Just as an FYI, under some circumstances, specifically if you have a pump or regulator in the fuel delivery system, you can simply put the 'T' in fuel supply line. Gas engines, YS engines, some OS 4-strokes, engines outfitted with Perry pumps or Cline regulators can all be T-ed without any problems. Since almost all of my engines are pumped, I normally use the T in the supply line...

I have a H-9 CAP 232 powered by a Thunder Tiger 120 (2-cycle). I use the dot system with the tee fitted on the fuel supply line to the Cari. I have throttle kill set up on my radio which closes the throttle all the way. I have never flooded the engine and it has worked fine. Just remember to verify that the throttle is closed before fueling. That's a mistake you will only make once.
