Yup you got it, clunk line out the side just behind the firewall and and back in a slot or hole in the cowl. Split at that point with a little slack and insert a 3/8 length of alum or bronze fuel tube. You fuel at that point toward the tank and you cannot flood or hydro lock the engine.

The hemostat is for a different reason, when you fully invert the engine as opposed to the 135 degree position suggested by the manual it is difficult to get the fuel tank low enough to completely eliminate syphoning so on those I channel out the top of the wing so the tank will set even lower. After fueling the hemostats are put on the line and it is plugged back in and they are removed just before starting. Often when fueled and sitting in the sun the fuel will expand and start a syphon.

With any inverted installation always hand pull an engine through while pinching that fuel line loop to confirm there is no hydrolock. Hitting a hydrolocked engine with a powerfull starter can severly damage any engine. If you have a hydro lock disconnect that fuel loop and pull the plug then spin the engine a few seconds with the starter, It will be obvious.

With the 135 degree mounting this problem is not a major problem however the hemostats untill ready to start are always a good idea.

The big YS fourstrokes that are used in this airplane for the gold class are not a problem this way as they untilize a completely closed circuit fluid pump system and cannot hydro lock while fueling or sitting.
