Yes, it can be used.
No, it's not the best way to run fuel to the carb.

That being said, I ran rubber 3/8" fuel injection grade line from the hard line on the frame to the fuel pump, then around the front of the engine compartment to the drivers side, & then to the carb inlet of my 6cyl. I ran it this way because I was continuously having a problem w/vapor-lock & needed to route the line farther away from the heat of the engine (the 6cyl had it routed over the exhaust manifold, or, the source of my heat).

It was about 5 ~ 6ft of fuel inj grade hose & I replaced it each spring regardless. I considered it cheap insurance against failure. I also ran double clamps on all of the lines.
