I used the Kirban fitting. I bought it from Casper's/John Spina. I then went to an airconditioning shop and purchased a screw-on fitting that fits it perfectly for the drain connection (you'll just have to take your Kirban fitting with you and match it up, around $6, -4AN I think). Then I used a long piece of clear hose and a clamp to complete it. Note that you will still have to remove the schraeder valve from the Kirban fitting and let the little bit of fuel spew into a rag when removed. I couldn't find a fitting that would press the schraeder valve as it engaged onto the fitting. If someone knows of one, I'd be interested in hearing about it.
