Those fuel line wraps for the pump to carburetor are probably not needed. This line is pressurized and therefore less prone to heat induced vapor locking.

I believe the practice of using these wraps is a carry over from the days of gravity fed fuel to the carburetor. Keeping the fuel line insulated did help with vapor locking. Also, placing clothes pins on the line to absorb heat was also another trick used back then.

Better to insulate the fuel pump from the engine and carburetor from the manifold.
