Dan, it's simpler Teeing off the bottom than drilling/welding into the metal teardrop tank for the second fuel outlet. Then that extra fuel grommet would be another potential leak. I was lucky to find a 1/4" brass fitting with three barbed fittings cast into it, so three less clamps and potential leaks to worry about. Compared to the engines' tiny fuel hoses, the steel lines and 1/4" hoses are overkill.
Since the fuel system has no pressure, leaks should not be a problem.
I'm glad I won't be propping up the bike into the tree anymore. This dual-engined monster must weigh at least 75 lbs.
