Fuel line size? I'm installing an LS1 in a 61 Impala. I know I need to run a return fuel line. My question is, what diameter should the inlet line and return line be? Also, I plan to install a sumerged fuel pump in the gas tank, what fuel pump presure should the fuel pump be?
I'm kinda hoping to use a pre-bent replacement fuel line for both the inlet and return, but I think it's only 3/8"

3/8" will be pleanty big, i would recommend using the 99+ Ls1 Fuel rail that way you dont have to run a return line. The fuel pressure is regulated on the fuel rail.
