1973 Volkswagen Beetle sat for two years, now won't start

my 1973 vw bug has been sitting for 2 years, i bought a battery and tried to start but no fuel going through fuel filter in engine compartment. what do i do??

If you have let it sit that long with fuel in it then every thing is clogged. Drain fuel, clear lines and that might do it .

clear lines? do i need to take fuel tank out and blow air through the fuel lines?

The car is a '73, run on gasoline that contains 10% ethanol in a car never designed for that. Your fuel lines, fuel pump and filter likely need to be replaced and the carburetor rebuilt. Drain the tank from the fuel outlet line, I don’t think you need to remove the tank to get to that fitting.
