Suprised that accumulator is -6AN, here's a pic...could it be? [914/6] Options

I ordered some parts from Summit for connecting my (hard) fuel lines to flex hose the other day. I assumed that I'd have to find stock Porsche fittings to connect the new fuel lines to the stock fuel accumulator/filter that's required for my 2.7L CIS engine. Just for the heck of it I tried one of the -6AN fitting that Summit sent me and (to my surprise) it seemed to fit the threads on the accumulator and the filter. Could that be right, Porsche using AN thread sizes for stock fittings?

One potential problem however is that the accumulator/filter fittings aren't tapered or flared for the AN fittings so what will I need to buy to get the -6 stuff to work? Maybe some kind of coupler or something? I assume it would leak without a flare on both pieces.

Here's a picture.

ok, you guys I may have confused you with the pic of the tube nut/sleeve..I'll be using that to connect the hardline (pictured) to the flexible hose [which is Russell (-6AN) Twist-on hose, rated at 250psi]. What I'm looking for is a connection from there to the accumulator. The hose I'm using would work better with the stock set-up I guess, since it's a slip on connector..but not completely necessary if I go with the Earl's adapter and "o" ring.
Notice the schematic that Dr.evil posted shows an accumulator with only 2 connectors but look at the photo that I originally posted and you'll see it has 3, one of which is on the other side. My engine is a '77 "s" and I think this is original equiptment. So I don't know exactly what that extra connection goes to. Ed promised to look through his stuff for an extra nipple and I really hope he has one.
