I suspect you are looking for AN fittings that mate aluminum tubing to AN 37 degree flares..."aluminum tubing adapters". I've been using mostly Earls fittings, but as you say, they start at -6 and go through -10 and don't include -4. 165006 at http://www.anplumbing.com/Adapters/Aluminum-14.html shows a picture of the -6 version of one. I'm sure one of the other manufacturers makes a -4 version of it. There's not generally a huge price difference between -4 and -6, and the flow is a lot higher, so you might consider going with -6 tubing and hoses if you get boxed into it. That's what we use on the Corvair, and what I'm using on the 2180 in N89JF. There's a picture of some of the aluminum tubing in the N56ML fuel system at http://www.n56ml.com/fuel/index.html. Before people spend a lot of time looking, exactly what do you need this fitting to do?
