Diesel Polishing

- The Workshop in Rhodes, Greece can offer diesel polishing for boat owners. Boats and yachts can often end up with the so called "diesel bug" or water in the diesel. This is more so with the new bio-diesel. Using advanced filter technology we will circulate the full tank 4-5 times in order to "polish" the diesel to rid it of all dirt, water, and growth.
Petroleum fuels always have moisture in them, dissolved moisture. It cannot be seen with the naked eye, but there are "Shell Tabs" that can detect it, when drawn through a tab attached to the end of a syringe. The process of fuel being delivered to the customer, sediment etc gets into the fuel delivery. Even service station tanks need to be regularly cleaned and drained of water that builds up in the bottom.
Very interesting! Good method! But please turn down the level of the background music! In fact, you really don't need any background music. .....
Exactly. I hate background music. It's SO distracting.
They dont address the issue of cleaning the tank around the baffles ( if fitted) as this is a great place for algae/bug to hide and grow.
They can pump/filter the tank 200 times if they wanted and if the diesel bug is present in and around the baffles just circulating it wont remove it. Had an Oyster yacht here that had its tanks professionally polished/done 3 times and then treated with and the diesel bug was back in 2 weeks to the point it looked like black jellyfish still inside the tanks when viewed the the Oysters tank inspection ports. I made up a old dive bottle fitted with a pressure washer lance handle and flexible nozzle and filled it with diesel and biocide then pressurised it to 200psi. It got in and around the baffles and removed 2 x 20 litre buckets of algae and growth. Tanks were then treated with the only biocide I trust and for the next 6 months until the Oyster went back to the US the tanks remained perfectly clear.
Very good comments, and cool idea about using a diving tank.
Polishing? When do do that ? Daily ,monthly Yearly? Is it for metal or plastic tanks ?
Excellent video and very useful logical explanation ... excruciating music though :-)
Dear PerI am impressed how you put Quality Products together for this. I am sailing in Dec 2018 from Spain to New Zealand. I have an old boat bought and I have a keel tank with no inspection hole. But I could Access the pipe which delivers the Diesel. I am interested to buy and construct exactly your System. You dont have to do this for free, I would buy even the components from you. Could you help me out. Thank you. AR
House water filters?
Can you please supply the components for a build locally in India.
Imagine you can use that on engine oil
Do you also add a biocidal compound or fuel stabiliser?
Lose the music please it takes from your otherwise great Video.
Funky annoying music
The music is really distracting
Dingle donk plink plunk la dada background noise that somebody thought would be good. The talking needs to be heard not the background.
Dear.
I can tell you how much the cost of a fuel polishing service is.
I am thinking of becoming independent in this business.
It's very interesting for me.
Thank you
السلام عليكم ..

You're Filtering the sludge through the 20 micron filter first before removing the water?
And not one comment on it.
The water destroys the filter element,
Remove it First
Muzika je da se useres.....
Can anybody tell me where to get the 2 20 micron diesel fuel filters? Can only find water filters that size and clear.
They are the same thing, water filters will work, also filtering through cat litter works
@@38KSW never thought of using cat litter thats a great idea to collect some of the soot and whatnot
#bin the music it’s not mtv.
Diesel engines are always “polishing” tank fuel. Fuel is circulated back through the tank again and again through water separators and filters. My Ford f250 truck has three filters, one of which is at the low point to the system and also has a water separator. If an undue amount of water collects there a sensor warns to simply open up a valve and drain out a cup or two until you have clean fuel. In 214,000 miles I’ve never had that sensor go off. This “polishing” process is not necessary. Marine engines operate the same way. There may be some benefit to doing this for distribution tasks where fuel is stored for long periods of time or a vehicle tank if it has not been stored without running for a long duration.
Marine engines are different in several ways.
They operate with much more movement, i.e. when the boat rocks from side to side in rough conditions gunk (diesel bug) that would normally be contained at the bottom of the tank (because it is heavier) is moved around and can be sucked in by the extraction pipe (which is always mounted a slight distance from the bottom).
They can operate in countries where it is harder to get clean diesel, and if you fill your tank with contaminated (diesel bug) diesel it will keep growing in your tank and the natural circulation and filtering is not enough to clean and totally remove it.
The so called Euro diesel which is now the only kind available in Europe is much more prone to diesel bug, and I believe that trucks have increased their filtering/cleaning capabilities for this reason, while smaller yachts have not.
@@perkjellqvist2329 ,.. Crossed both oceans in sail boats and years of coastal in both sail and power and so this based in experience. If a boat isn’t run and used the fuel can go bad as you say. AND “polishing” would be warranted. If run in that condition, high pressure pumps, common rail and injectors are at risk. However, even moderately poor fuel at fill up would be cleaned by normal consecutive usage even out to sea. When bad fuel is the norm filter need be changed often and water drained from separators when observed.
@@Doc.Holiday What you say is true but anecdotal, other sailors have different experiences. All I can say is that I run a yacht maintenance business in Greece and we are called out to totally clean diesel tanks on sailing yachts on a regular basis.
@@perkjellqvist2329 … I take umbrage with your use of the adjective anecdotal. My statement(s) above are both true and reliable. You provide a valuable service to floating marina condos that are not used. A yacht that is actively run, used and serviced by a knowledgeable crew and/or owner has no need of such service.
@@Doc.Holiday With anecdotal I meant that it is based on your experiences. Situations vary widely around the world and not all sailboat owners have the same experience as you. As I said in my first reply, all it takes is filling up once with with diesel that have heavy growth and the standard circulation cleaning found on standard sailing yachts might not be sufficient. My anecdotal experience has been confronted with many such yachts and situations.
I also said that I agree with your reasoning that in most conditions the standard fuel filter and extra water separator circulating the diesel is sufficient.
I will add that I too take umbrage in your condescendingly calling my yacht clients "floating marina condos" not actively run, and not serviced by knowledgeable crew. As I said situations vary widely around the world and in varying circumstances. Ideal circumstances are not always present for everyone regardless of their experience.
I will continue to clean infected (by diesel bug) tanks as long as there is a need.
