Re: fuel pump problem...?
Give the tank to pump line a thorough inspection. Look for anything that could allow the pump to be sucking air into the line instead of fuel from the tank. Like a crack or split in one of the rubber hose sections. Or a tiny rust hole through the steel line.

Re: fuel pump problem...?
had the exact same thing happen to my 85, finally replaced the lil paper filter in carb and it fired right up, couldnt imagine a lil filter blocked so bad that it wouldnt allow gas to get into carb
