As i continue to research the work I will need to do to install the efi system, my mind has come to the issue of the fuel tank. The fuel system will be a return setup so i need to know the following: -Does the stock tank have a vent? -What is the stock fuel line size? -Does anyone actually have a diagram of the fuel system for a stock car? I remember taking the fuel tank out of my 71 and had to disconnect so many damn lines that went up to that weird fuel block behind the rear seat. What do all those lines do? Thanks for the help.
Powerjection III Wow, so there are 3 vents all going into that standpipe (which is in the cabin of the car) and it has what seems like a line that comes out and goes to the front of the vehicle (charcoal canister????) And, the tank has a return line as part of sending unit? Where does the return fuel come from? And does anyone know the ID of the feed and return lines?
