Coyote fuel rail connector

[Junbug]

What are the different methods of connecting my fuel pressure regulator to the coyote fuel rail. Pic below is what mine looks like. I'm guessing a compression fitting that will connect to my 6AN fuel hose? Should I use the snap on fuel line connector sent as part of the kit? That one seems sketchy as I would think it would fail under pressure. Any advice is appreciated.

Hey Bryan - I made all my fuel lines out of 3/8" stainless steel. Rather than trying to make my own -6 AN flares, I used these compression fittings from Breeze. They're super-easy to install and work perfectly. I also used one of these compression fittings on the inlet line to the coyote fuel rail.

X2 on the Let-Lok compression fitting JohnK described and pictured. Used those on both my Coyote builds and also the LS3 in my truck. Rock solid and directly connects to an -6 AN hose.

Throw those quick connectors from Factory 5 in the trash, unless you want to see what fuel looks like dripping on your engine.
I replaced them with a name brand from a parts house.
The compression fittings look like the way to go.

Here is the conversion fitting I used from Russell, Push-On EFI Fittings 644123. I used this fitting on my 2nd Gen Coyote fuel rail.
