Ah, the joy of P.O's

If you are talking about the 2 lines that went to the charcoal can than yes they can be looped. At least when I got mine they were looped (still are) and it runs fine. I believe the gas caps are vented.

If they are looped how does the tank breathe? I have no doubt it works , the p.o. obviously drove it that way, I am just curious on how. Have a new sending unit on the way should be running by the weekend

If it were me I would hook it all back up like it should be.

If they are looped how does the tank breathe?

If the outlets are looped the system is force to breathe through the carb from the return line. A vented fuel cap has a one way release valve and only vents one way, "in" not out. As the fuel pump draws fuel it changes the pressure in the tank. When the pressure reaches a certain point the fuel cap valve opens to relieve pressure in the tank.

Hope this helps.
