Which fittings am I looking for? Factory fuel and evap line to -6an??
I'm changing fuel rails and am using the factory feed line as a feed and the evap line as a return. I need the fittings that mount to the factory lines and go to a -6an threaded end. Anyone have part numbers?????

Thank you very much Chevy Chad. One question thought, the Summit feed line fitting says 10mm to 3/8th. I'm assuming the feed line is 3/8th. Don't I need a -6an to 3/8th? Because the EVAP line is -6an to 5/16th.
The main thing I need was the 3/8th and 5/16th sizes.

I'm getting ready to install my new Speed Inc rails and I'm trying to determine if I need to keep the evap line from the LS1 manifold and hook up the evap pump back to the evap line as well?
Is there any way to get rid of the evap pump? Manifolds like FAST or PP don't seem to have these hooked up.

BeaSST: Few things here...
The EVAP doesn't have a pump. The EVAP line runs into the manifold so that it pulls vacuum. My car is a forced induction car so I disconnected mine so as not to force air into the EVAP line. Seeing as how I disconnected mine and it didn't hurt anything, I would have to say that pulling vacuum from the EVAP line is like your tonsils. They're there but they don't really serve a vital importance. If you wanted to, you could just vent your EVAP to air or relocate it to the hard line to get rid of some of the clutter.
The reason I am using my EVAP line as a RETURN is because I am running a boost-referenced fuel pressure regulator to increase my fuel pressure at a 1:1 ratio under boost. If I was only going to stay at 600rwhp or so, I would just leave the fuel system stock using the in-tank FPR and factory chintzy, but functional, return.
I'm assuming you are simply doing the rails because you like the look or got a hell of a deal because the factory rails can support 700rwhp. Anyway, you can hook it back up or relocate it. Just do a search for EVAP relocation and you'll find a write-up.

Chad,
Do you know where I can find a fitting that has the male end of a quick disconnect on one end and a barbed end on the other? The barbed end needs to be for the return size which is 5/16" I believe

I keep these in stock. Russell makes both 3/8" and 5/16" to -6 Summit has it listed wrong or they have a part I have never heard of. You need to keep your EVAP vented or your fuel tank will hold pressure.
