I am in the process of taking out the fuel lines for the EFI V6 and am going to run a 3/8 steel line for my V8, I was considering where would be the best place to put it. I havent installed the SFC's yet, and will have true dual exhaust. I am kinda worried if I run the lines, that they will cause problems later. Thanks for any help.

 

What kind of fuel pump are you going to run? If the in-tank electric with regulator, just use the V6 lines to the engine compartment, plumb your regulator on the driver's side then over to the carb, using the stock return line, you're done.

If you're using a mechanical pump, the factory ran the lines up the driveshaft tunnel to the tranny tunnel, over the top to the passenger side, then up the frame rail to the mechanical pump. Couple of problems with that: 1) The factory V8 carb cars have a stud and strap tack welded to the top of the tranny tunnel for a clamp to hold the line up, and 2) It gets pretty hot up and back there.

I just ran a metal line along the front of the front cross member from the factory V6 line to the fuel pump, with a return line parallel to it to the factory V6 return line. It stays cooler there, and is well enough protected to not worry about damage. I found some tie wrap studs that press into 1/4" drilled holes that I used to support the lines where they go on the crossmember.
