The main line goes to the input of the mechanical engine fuel pump. The reserve line goes to a "T" on the output of the mechanical pump. Typically all these fittings are -6. There is no return line.

I'm not sure what you have exactly. The standard Shelby fuel system works fine, and you shouldn't need all sorts of large fittings and complicated fuel lines. There are a lot of 500hp and 600hp Shelby cars running around with the standard setup.

Thanks Kris,
I am not running a mechanical pump. I Have the two -6 lines running in to a fuel block and then running out to a fuel pressure regulator and then to a fuel filter and then over to the fuel log so the line that should have gone to the mechanical is acting like a return since there is less resistance than the other way. Hmmmm.... Now what?
