It sounds like you connected your tubes to the main fuel intake since you said you have a hard time starting after draining the carb assuming you're starting with the petcock in the "on" position not "reserve".
Yes, it was F-4040-A. The ethanol is ~10%. I just used slip fit, but the slip fit was very tight before the Tygon expanded.

The petcock in my Acerbis tank has 1/8" FPT that the nylon flter screws into. I took the filter out (there is another in the fuel line) and put a short barb fitting in its place. I no longer have a "reserve", but don't need one since I can see the fuel level through the tank.
