Fuel lines

I have a 47 CJ2A that had a F-134 installed in it. The Jeep has been sitting for about 33 years. With old fuel in it. Thinking of replacing all the fuel lines and gas tank. If I order the replacement lines for a CJ2A am I going to run into issues, or should I get new lines for a CJ3A?

You should use the original setup. The F and L engines had the fuel pump in the same place.
