Why is my carburetor not getting any fuel?

I have 73 monte carlo with a 350 engine and 4 barrel carb. The engine suddenly stopped running while driving on the freeway. The engine just stopped running(it didn't overheat or nothing). I'm getting spark. The manual choke 4 barrel is not getting any fuel though. I've done the following related to fuel: 1. Pulled the choke- no fuel 2. Pulled the fuel line connected to carb, bumped the engine, still no fuel. Replaced the fuel filter. 3. Bought a new fuel pump and installed it. Tried to start, but it still didn't start. 4. Sprayed carb cleaner- still won't start. 5. Removed the fuel line connected to the fuel pump, bumped the engine, and fuel came out of the fuel pump. 6. I disconnected the fuel line(carb to fuel pump), blew it out, reconnected it, and it still won't start. The battery is brand new. I beginning to think the fuel tank("sock") is plugged. The car has about a 1/4 tank of gas in it as well.

Before replacing the fuel pump and filters there could be clogged pick up in the tank causing thr fuel pump to not get fuel to pump.Or a issue with the carb float not allowing fuel into the carb?The first thing you have to check is if your getting fuel to the pump?Not just lets throw parts at it and see what sticks.

The sending unit and float tells how much gas there is it doesn't effect the flow of gas.The pick up with the sock on the end of the pick tube effect the flow of fuel.
