OK, I will use the two line system with a "T" and a fuel dot. Where do I take the vent line? I know it does not go to the muffler. Should I treat this like a crank case drain line and let it hang under the engine? Oh yea, IS there a crank case drain line?

My Zenoah G45 and Slimline muffler make for a pretty tight fit in the lower cowl section of my aircraft. The vent line would be very close to the hot muffler. Any issues? Thx.
