Someone out there sells a silvery cast quick disconnect for cheap that actually looks very, very trick.
I run a fuel pump on my bike, and put the female end on the line going to the pump.
A male end is on the line coming off the fuel tank valve, and another male end on the purge bottle fuel line.
It works very, very well...
I can take pics of my setup if you'd like...
Aside from richening up the circuits in your carb to flow twice as much, don't forget to close the spark plug gap to .018 to .020.
