Re: Howes fuel treatment

I just want to get to the heart of this long discussion.
I have 30 years of positive experience with a full tank and an additive for diesel. There was never water in the tank and organic pollution. Last year I was so smart not to do this because lack of wind had covered a distance of 1500 SM under motor and had refueled several times. The result after 2 months in the port with a 1/4 full tank and without Grotamar (additiv) in the diesel was a complete algae infestation of the tank and lines before the winter break and the refilling of the tank.
I can highly recommend filling the tank completely with the addition of a good additiv at every opportunity and before any longer standstill.
There was a great deal of effort in cleaning the tank and completely replacing the lines and the filter system.

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.
