This is the post were I detail how I ran the fuel lines:

Yes, 2 lines. The line on the driver side is a reproduction pre-bent line I bought from Inline Tube. It fit very well. Stock, this would be the fuel supply line. I'm using it for the return.

I used NiCopp tubing and bent it myself and installed it on the passenger side routed as a mirror to the other one. This is the supply line so I installed an EFI fuel filter on the frame rail in the middle of the line. (I will use a Walbro in-tank fuel pump.)

The supply line connects to the passenger side fuel rail at the front where the pressure sensor is. The fuel rails are tied together on the back side and the 58 psi regulator is mounted on the front of the driver side fuel rail and the return line connects to that.

It's a non-adjustable regulator that is an Edelbrock part. When the engine was run on the dyno, it did run at 58 psi so it was right on the money.
