Capt. Wil, Could you please explain for the list how your polishing system will clean a tank without the tank contents being stirred up in a seaway? I believe that you do all your polishing at the dock. Does the high capacity pump agitate the fuel sufficiently during the polishing and therefore get out the "stuff" that is on the bottom of the tank? I have the polishing pump you use and will install it next spring. I am hoping that the system will remove the crud in my tanks as it is a major job to clean them manually (it requires removing both my fuel tanks because of the lack of room to access the inside). Thanks, Herb Hoffman My Tyme Prairie 29 -----Original Message----- snip >The described system will clean up a dirty tank and keep it clean.
