I recently cleaned the fuel tanks in our 20+ year old Amazon prior to a trip from La Paz
. For all the obvious reasons, I did not want sludge fouling the filters. We bought the boat about 2 years ago from the original owner. She had not gotten much attention the last 10 years, and from the condition of the gaskets on the inspection ports
, I don't think they had ever been removed.
My tanks are also baffled, and the inspection
port only allowed access to the lowest point of the tank for cleaning
. In my case, I was astounded when I removed the covers and found zero sludge in the tanks, and only a little grit. I had bought a case of paper towels to clean my four stainless tanks (total of 300 gallons tankage). I used a roll and a half cleaning
out three of the tanks. The fourth was under the water
heater, and based on the condition of the first three, I elected to forgo the process of removing the water
heater to clean the last one.
I had a question on an earlier post. Why would you think 50 year old stainless fuel tanks would be at the end of their life? After 20+ years, mine still look new.
Also, I noticed the original poster made a statement about aligning his fuel return to a different tank than he was drawing from. In my opinion, this is a risky practice that can lead to overfilling a tank and a fuel spill (in my case) into the bilge
. I had a mess to clean up after I found I had pumped about a quart of diesel into the boat. The smell of diesel alerted me before I pumped any more.
If you are going to return fuel to a different tank, I would be extremely watchful of fuel levels. I certainly would not do it as a standard practice when running the auxiliary.
