I'm setting up a 235 with a 2x1 Offy intake and 2 Rochester B carbs. The fuel pump has 1 outlet and there are 2 carbs. How do I get 2 lines into the carbs?

Additional questions:
What size fuel line is needed? (tank to pump, pump to carbs)?

Is a stock 1960 235 fuel pump sufficient for a 2x1 setup?
