Depending on the path of the fuel line, the leak may siphon back to the tank. If the line is building corrosion, you're probably better off replacing the whole line. If the source of the blockage is not from the line, then you may have some sludge in the bottom of the tank. With a little bit of tape and a can of canned air (for blowing out electronics), you can try blowing back through the fuel line. Canned air is inert and low pressure/low volume, so it'll be safer than compressed air, just not as efficient in clearing blockage. If you test it with a friend, you can also listen for leaks and bubbling in the tank.
Have you tried verifying that the fuel pump will pump to the carb? What about the filter?
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
