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.

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
