[C320-list] Fuel polishing/fuel tank cleaning

[millers1 at aol.com]

Greg,
I am not sure if my posts make the site (?).  let me know if this shows:
I have not polished my 320 fuel tank.  I did replace the tank after a weep develpoed a year ago.
When I inspected the old tank their was no real contaminate in it that the Racor filter wouldn't have
handled. I replaced the tank. (new tank and hoses, etc was about $550 as I recall).


I have never had an engine stall out even in serious storm conditions where the boat was being shaken up pretty 
good for 3-4 hours.


I have had Racor filters on the 4 boats I have earned and never had an engine issue.
I never really find and sludge or water in the Racor or the Yanmar engine filter.
I presently have a 2 micron Racor installed (grabbed the wrong micron when bought).\
I believe Yanmar recommends a 10 micron be used.


I have twice been aboard a 36 Catalina when the owner had the fuel polished by two different companies.
Each time the contractor stated the polishing was effective for gunk removal... not so good on water... rely on the
Racor filter.  The costs were $150. and $225 (inspected with camera...etc)


I also try to buy fuel at a power boat dock, they use lots of fuel and it is usally fresh.

Does anyone have their fuel tank cleaned and the fuel "polished"? If so how often?

Has anyone ever had an engine failure due to water or debris getting to the injectors?

How much faith do you put in the Rancor fuel filter removing any water from the fuel? What size filter do you use? 10 micron or 2? Other?

Sorry for all the questions. But I am interested in what others do and their experiences in fuel management. Calder is very serious on fuel cleanliness. However, my sailing neighbours seem unconcerned and no one I know has ever done a tank cleaning/fuel polishing here. I had two quotes for servicing my 20 gallon tank. $1100-$1200 Cdn or about $900 US.

Thanks,
