Dennis, I've watched for return flow from the injectors and been quite disappointed. Hardly any and certainly not enough to suggest that it is "recirculating" the tank.
I hear what you're saying regarding the agitation not being sufficient. Its always a question in my mind of just how bad is it in there? Is nothing coming out cause its clean or cause its stuck?

IMHO, if it is not strongly agitated, sediments will remain in the corners of the tank. The first encounter with rough seas and you will blind your fuel filter quickly. The best solution is to either remove the tank and clean it. Second best is to drainit, install a fuel compatible access port in the top and clean it manually. Third, have a professional clean it with a high velocity wand inserted through the fuel sensor port. If you can't do any of those and choose to recirculate it using the engine, install an Algae-X unit ahead of the fuel filter. http://www.diesel-fuels.com/algae-x/magnetic-fuel-conditioning.php Install a vacuum gauge downstream of your fuel filter to give you warning when the element is beginning to blind. If you have a Racor 500, get the vacuum gauge that replaces the T-handle. Carry lots of spare fuel filter elements. Dennis C.

I think that the tank is about half-full. At the suggestion of one of our contributors here, I will patch in a 12v. pump and recirculate the fuel through my Racor filter for a number of hours in an attempt to polish the fuel. That said, do you think I am better off trying to burn off the old fuel as much as possible before putting in new (if of course the engine appears to be running well), or dillute the old stuff with new? Finally, does anyone here have experience with Starbrite Star Tron Fuel Tank Cleaner? While its NOT cheap, I'd rather start off with as clean a fuel system as possible. The reviews seem to be good (and Practical Sailor rated their biocide highly), but I don't believe everything I read on the 'net... :) Thanks in advance!
