LS Swap Fuel Lines?

There are three lines running along the frame on the TJ, I assume evap, pressure, and return line? I have a return style fuel rail on my LS. My question is on the pressure lines and return lines, what are the sizes on the TJ and LS and what are suggestions on how to connect the Jeep lines with the LS fuel rail?

I ran a 6AN pressure line from the LS regulator to the engine and completely removed all of the Jeep fuel system. I also made the short return like Novak suggests.

I am using the Fragola brand. From Jegs. I was having a hard time with the specs on those Amazon brands. Fuel line can be funny in the details. Especially in the push on hose style. I am also putting the crimp type clamps on the hose.
