Fuel system setup for ls swap

I have seen lots of info about a return less fuel setup. The engine I purchased has a feed and return line with the regulator on the fuel rail. Is it as simple as running a feed line from the fuel pump up to the rail and a return back to the tank? I am about to order some fuel hose and want to make sure I am not missing anything. Thank you for the help.

Yes, 3/8" high press hose to the rail with some type of filter and 5/16" return back to the tank.

Your the man. I am thinking about running a fuel cell from summit and it has a -6AN vent fitting. Somebody mentioned something about a one way valve for this fitting. Does anyone know of a part number or what type of fitting/valve i need?


On a side note, is a special tool needed to remove the factory gm fuel lines?

Roll over valve, Like this:

The line disconnect tool isn't needed, just squeeze the tabs push together than pull for the plastic kind. If you're talking about the metal internal finger kind, I use a small screwdriver and work them out.

Re: Fuel system setup for ls swap

the gm fuel line tool costs like $5 for a 3 size pack, I was hesitant at first but after breaking a plastic ones off, I sprung for the tool.
