metric to -AN adapters

[A Quiet Boom]

Can anyone help me with sizes and a source for metric to -AN adapters for a 3.0 fuel system? My car is carburated and I need to run lines for my 3.0 fuel system. I have 25' of 3/8 aluminum hard line lying around that I'd like to use but I need to adapt it to the engine and fuel pump as well as tank return inlet. Another question I have is where does the pressure feed line hook up? Does it hook up to the fuel accumulator or the line on the engine? I can't find a good schematic of the fuel system so I don't know which line is which.
