Pics. One from my '54 Manhattan (fuel line enters rear of carburetor) and one from my '54 Late Special (fuel line enters at the front). Note the in-line fuel pressure regulators for the added electric pump. I don't worry about "judging" so this is the way these lines have been routed for over twenty years.
The Manhattan line is a rubber hose entering the rear of the carb.
The Late Special is the metal line entering the front.
