It has AN fittings because it's a fuel line check valve.

Can't think of the name off hand, Hippy. I know it was way cheaper but didn't come apart.
Wasn't it like $60? I want to say sifton but can't seem to find it.

There's a "Sifton" part that appears to be threaded on one end for some reason, no idea if it's rebuildable.

There's also a V-Twin part (40-0875) that looks rebuildable. Appears to be a direct clone of the KVP.

I know there was one on ebay that came with a spare umbrella and all sorts of things that doesn't seem to exist now though.

Reed valves are suppose to be pretty consistent although I'm not sure what they actually do to the CC pressure.
Some use a reed valve from a 2 stroke.

It may be in the CC pressure thread... think it is. I'll check.
But it's a CC breather and cheap. Looks like the Hayden.
Maybe the Vtwin as mentioned by sml1226... think it is.
We never got the follow up on it as I remember though.

AN fittings are not unique to fuel lines. They are used on oil lines, fuel lines, coolant lines, etc., particularly on race cars and aircraft. 8 AN translates to about .5", and I've seen up to 10 AN.

What you linked to is a fuel line check valve.

Dammit that's a long thread...
I think the Vtwin is the Hayden knockoff.

edit:
Here is the Sifton for about $33 plus shipping.
It looks to be single use (not rebuildable) but that may be alright for your needs.
https://www.ebay.com/itm/SIFTON-CASE...cAAOSwzrxUuDhJ

I haven't found the one I was thinking of yet.
Panic cycles had one but there add is not working on Ebay.
That also may have been the one I was thinking of.
It's single use also.
