Routing new 1/2" fuel return line. How did you go about doing it?
Well, I found out my return line back to my tank is well too restrictive for the fuel pump I am running. (Walbro 255lph) I have the Mallory 4309 regulator and a holley DP carb. The pressure would not drop below 10-11 psi so I am going to route a larger return line. What is the easiest, or the best solution in doing this? I'm more or less confused on what i have to do once I get the new line back to the tank???
Thanks for the input.

The pump mounts to the return line on the pick-up. You either need to replace that line in the pick-up, or run another one.
