Hi all, does a blower motor w/ carbs need a return fuel line??? I'm going to need to up-grade my fuel system to install that Hemi in my '32. I only have a 3/8" outside diameter fuel line now so I think I'll need a bigger fuel line, I need to get an electric fuel pump, filter, etc. When I run my fuel lines in my frame I'm wondering if I need to have a return line. Thanks! Bill
