I just posted a reply to another thread regarding diesel fuel tank cleaning
I was educated by the guys( www.perfectfuel.ca
)that cleaned my tanks
on my 41 ft. Grand Banks
I was changing filters at least every 30 hours, and no amount of tank treatment was helping. Finally I cut open one of my filters to see what was going on. There was a wax build-up on the filter element and a very distinct sludge on the bottom of the canister. I keep my boat at my residence on the St. Lawrence so I called Perfect Fuel
. They came to the boat, took some fuel
samples, showed me the crud in the tank, and proceeded to clean the tanks
I won't get into the technical aspects (that can be found at their web site) but needless to say, it was a learning
experence. They took enough crud out of my tanks to fill 20 filters. There was signs of water
, sludge, and actual hard dirt in the tanks. They cleaned about 400 gallons of fuel. The job took all day, but in the end, my fuel went from a black mess to clean and clear. The filters no longer clog and we run to Quebec
City and back without the engines giving a hint of black smoke or making a mess of the transom.
Moral of this story, maintain your fuel properly, forget about all the junk fuel additives out there and find a good one. I use Algae-X AFC 705 mixed at 5000 to 1. My diesels run much better now, my generator
run's better, and my diesel consumption
has decreased. Best thing is my wife no longer complains about the smell of diesel.
