Is the racor before or after the racor? If it is before I would replace it. I change my spin ons pretty regularly espescially with this ethanol crap we get now. Also what fuel line are you running? Make sure it is a new style marine grade line as most automotive lines are not meant to run under a vacuum like an outboard does. Verify the tank vent is good. I pulled the one out of my pro line even though it looked new and it had a big chunk of corrosion inside it. It still flowed air, but not enough when I dropped the hammer. Also if your tank has a anti-drainback valve in it, pull it out and clean it. Over the years that check ball gets varnished pretty badly and will cause it to obstruct the fuel pick-up. Most people just remove the check ball from them to prevent from having this problem. Start with basics and go from there. Also I like to use marine grade EFI fuel line as it is HEAVY walled and will not collapse even when you are hammering down on it.
