I run a couple of loops of fuel line on top of the tank, straped down against the tank, then run it out the fuse.

very simple, I think there is a kind of air valve from the outside air can enter but can not remove the air or gas.

does not drip out of gas?

The extra loops give the fuel extra travel distance. I havent noticed any fuel dripping out when I held it inverted. I usually do 2 or 3 loops on top of the tank.

No problem, I too was researching this just a couple weeks ago and in this case pictures really do speak a thousand words. Again can't take credit for the work, found on a forum somewhere (might have even been here) but worth sharing. Think the pics have a name on there just hard to make out.

Buy a quality fuel dot and stick with the two line system. No need to overcomplicate it with three lines.
