Fouled Fuel Tank
« on: August 14, 2001, 09:10:32 PM »

My family and I went on a week's cruise in Pamlico and Albemarle Sounds in North Carolina last week.  The diesel engine conked out half way from Bear Creek to Ocracoke.  This has happened before and I replaced both the fuel filter in the fuel-water separator as well as the second stage filter on the engine. (I have now replaced both fuel filters 3 times in the past three times since I bought the boat in May, 2001!)
 To make a long story short, I finally concluded that the tank itself had so much algae/slime sediments that it was clogging the fuel intake line even though I have been putting anti-bacterial additive to the diesel fuel with each new filling.
 The dockmaster at Anchorage Inn Marina, Ocracoke, suggested getting the tank cleaned out and re-filter the diesel fuel before pouring it back into the tank by a professional.
 Has anyone successfully cleaned out his diesel fuel tank?   I am thinking of removing the fuel gauge and stirring up the inside of the tank with a brush and then pumping out the stirred up mixture of fuel and sediments into a big vat and then filtering the fuel before pouring the diesel fuel back into the tank.

   Out here in CA. there are companies that come to your boat and "polish" the fuel. It involves running a hose into your fuel tank and pumping it out and running it through a series of filters to clean and remove all the impurities. I had it done several years ago when I was having problems with clogged filters. From what I remember it was a little costly, but worth it if you are having to replace your filters all the time. I think it was less money if you take it to them to have it done. One benefit is that they do warranty their work if you have a recurrence.

I had the same problem a few years ago. I had the tank "polished" as they call it and the fuel cleaned and replaced into the tank. It totally solved the problem and was well worth the $200 they charged for it.
