Tanks and Spindles and Booms Oh My!

We had our fuel tanks cleaned 17 years ago after buying our boat, after that I installed a algae X device, also have used AFC 705 fuel additive and zero problems, I use to sell Algae X before retirement and I am a true believer. The guy who cleans fuel for a living uses a large Algae when polishing fuel. Check it out, lots of information. Good luck, love your videos. Keep up the good work.

Diesel fuel lasts a very long time. Older fuel tanks need to be cleaned because sludge forms on the bottom which eventually works it's way into the engine's filters. There are additives that help slow the formation of the sludge but sooner or later it will form up. That one tank looks very easy to clean. I would pump the fuel out and store it for later use. Next inspect the tank. If it is dirty and sludgey you can expect the other tank to be just like it. If it's not bad I would pump the difficult access tank through a 2 micron filter into the easy tank. Harbor Freight sells a borescope that you can insert through your fill tube on the difficult tank, inspect it and if it's bad get it out and make a service access for future cleaning. When the tanks are clean, pump the old fuel back in through a 2 micron filter. This time put the addative in and do that at every fill up. In 1979 my friends father pumped World War II home heating oil into his Ford Lehman diesel and ran it all season with no issues.

See you next then , nice video !

Hi, we have a similar old diesel tank and figured out a system that works fine for years now. We installed - as first filter (closest to the disesel tank) a cheap automotive diesel filter (transparent housing, paper inside) we placed it in a way that there is good access to it and visible as soon as we open the engine compartment. We used clips on both side of the filter that you can tighten and untighten by hand. We have quite keep quite a few of these filters aboard, one spare is always placed close to the filter in use, in the engine compartment. From tiem to time - especially when rough sea or before entering to port - we take a look at the filter and change it to a new one if needed - a one minute job, no tools are needed. The other filters in the line are all behind this cheap filter - ever since we never had to clean the other filters (those are much more difficult to access and clean).

Nothing wrong with the fuel pump it into the other tank or into the Jerry cans clean the tank and inspect it

I have heard there are places to buy fuel which should be polished as a matter of course. I am a firm diyer. I have only one fuel tank. You can suck from one tank pump through a filter into the other tank. There are all sorts of options available. Use your existing filters with a y-valve to send fuel to the engine or the other tank (with skill and planning you can maintain your line pressure.) T on a vent line to fill the tank. Use y-valves to swap source and destination tanks. Make it a portable system to provide the service for a fee. Your personal system can operate at a few gallons per hour. A business system should be much faster and probably have two stages of filtration. That motorboat down the dock got water in his 500 gallon tank. Charge him $0.50 per gallon to polish his fuel.

gill its good that you got so much room to service the tank ,i wonder if a guy could use an old tire tube to make a new gasket, if the tank is not leaking ,it looks good.

your diesel fuel , in NE farmers will take it to run their equipment or friends that have recycled oil heaters will also run on diesel so will floor heaters Again we live in the cold NE but that's my recommendation

Yeeey u followed my instagram and on ur post i saw be our 2400th subscriber and here i am its me made it u were on 2399💪 subscribe if u líke and hopefully we meet someday ,il start my world trip end 2019 but Starting with episode 1 very soon as ive just bought my blue water cruiser⛵❤ regards from the Canary Islands 🤗

I would contact a fuel polishing company, or even better set up your own. The advantage of fuel polishing is it pumps the fuel at high pressure to break up any crud and sludge in the bottom and filter it out. There does seem to be big difference in polishers though.

if you cant find a place to dispose of the fuel then i think you need to bite the bullet. would be hell if you find a problem with it after everything is back together. have you ever considered installing a fuel polishing system in the boat? depending on how much they want to charge it might make sense to just install your own.

The fuel is fine. Add Startron diesel formula to one tank, then transfer contents from other tank so that all is in one tank. Wait 24h then transfer all to the other tank with a 30 micron filter in the line. Diesel when kept clean like this is good for many years.
