An intake pump works fine with a carb but you'll need a return line. That is actually the best system for a carb but it does involve running the second line back to the tank. The return line setup always has fresh gas at the carb so it gets rid of the fuel line boiling issue on hot days or other such problems.

You should be able to buy a brand new tank for an E body that is already set up for an intank pump. So it is almost a plug and play type of deal these days.
