Re: Howes fuel treatment

There is a third reason to keep the tank reasonably full. As the tank gets closer to empty the sloshing of the remaining fuel at lower levels will begin to stir up that sludge cocktail at the bottom and it will begin to enter your fuel system. You can see it in the Racor bowls, if may increase your vacuum gauge if you have it in the Racor and it can clog your fuel line.
Last season another boater (non Amel) had engine trouble and changed his fuel filter. He then experienced air seeping into his fuel lines around the Racor connections. In the end it turned out that was because his fuel line was so clogged. He borrowed my suction fluid extractor and sucked about 20 liters of crud and fuel off the bottom of his tank before he had it clean enough to proceed. When they were stopped they were not in a location with easy access to fuel polishing services. He believes what broke it all loose was a very rough passage with low fuel levels.
