Help find fuel quick disconnect line..... purty please?

So I found what I'm looking for, but it's in Australia. I would prefer to have it much sooner than than the company could ship, so I'm reaching out to you for help.

M12 banjo with a 5/16 quick disconnect efi setup. Super simple, but I don't see anything stateside. Maybe I'm looking under the wrong keywords. Maybe it's a rare part. I don't know. What I do know is I don't want to cobble together three AN fittings to a banjo to do what one single part could do. Reducing parts involved is the whole point of finding this anyway.

Please help!

Looks like below, but American. Or at least in America.

Not sure if this is useful but . . . that resembles the "Lincoln" style of quick disconnects, but for air hoses. 

Have no idea if it is available but Pegasus Racing seems to have a lot of of hard to find stuff.

Can you deal with a more regular barb?

Unless I build a whole new hose, no barb.

I found this one from Mityvac but no clue if it's 5/16" connection. Looks larger like 3/8" from my untrained eye.
