We just went through this on a friend's boat. The boat was abandoned for years and in the end we had to replace the fuel tank. Some things to keep in mind: 1. A professional fuel polisher set up, either installed onboard or used a fuel cleaning service, has much higher pressure and volume than you will get by using the lift pump to recirculate the fuel. 2. If the pickup tube has a screen, you will go nuts with random pieces of crap clogging it and then falling off later. 3. Vacuum gauges on *each side* of the Racor are vital to determine if the tank pickup is clogged or the filter is clogged. 4. If there is a way to remove the fuel tank, do so. I cleaned mine out with my garden hose and soap at home, but only them realized there was no drain at a corner to get all the water out. My wife thought it was funny watching me jump around in the yard with the tank over my head getting the last of the water out. That was followed by a couple of methanol rinses to have a perfectly clean and dry tank. YMMV on how to do this, but you need to see into the tank. 5. 5 year old fuel - yikes! Get rid of it.

If you don't, the readings will be wrong - sometimes way wrong.

That's what I did when I bought my 32 Tom Anderson C&C 32 Nonpareil Marblehead, MA 5 hours to next race ??
