Hi Bob,

I used a barbed coupler - something akin to this from McMasterCarr. You can get them in various plastics, brass, and stainless. You might also find them at your local auto parts store, too. I used a "tee" version so I could run a line up to the LSE-II ignition. For completeness, I soaked mine in avgas for a couple of days to test for fuel resistance.
