    Does anyone happen to know the actual inside diameter of the OE fuel feed line that runs up to the fuel rail?
    How about the inner diameter of the OE fuel rail? I'm trying to determine what size AN line is larger than the OE feed line (-10???), and if -6AN would be enough of a return line for an Aeromotive 1000 regulator on a 700-800 WHP e85 motor??? Would the OE fuel rail support a return system? TIA

    8AN is much bigger than the factory feed line and is common on aftermarket fuel systems for these cars.

    5/16 is the the line size, but I don't know if the line to the rail is the same
