Hello Maja! Thanks for sharing. Two paralell filters is a good setup. My setup in my sailboat are two fueltanks, starboard and port, quite high up in the hull. The tanks communicates via a manual valve and hose. (Yes, the valve needs to be closed when sailing). SB tank is the ”main” tank. Filling, consuming, levelsensor and engine return is done only to this tank. You can think of Bb tank as a spare tank. To use the fuel in Bb tank I have to open the communication valve for a while. The communication hose is big, 25 mm. However the method I chosen is to consume fuel from the bottom of the tank, note bottom, meaning the absolute lowest point in tank, not a pickup tube. (You mentioned a drain valve). The effect is that all contamination is removed from the bottom of tank itself before it can create nastyness. So by inspecting my filter I can judge the amount of dirt in the fuel and any condensation is removed from tanks and gets collected in the filter. After 15 years of use I inspected them and found no dirt or rust on bottom nor in the top. Conclusion is that the condensation etc are removed from the tanks and the Racors are doing their jobs. Winter condensation (Scandinavia!) is minimized with full tanks. The tanks ventilations is done high up under the cockpit coaming behind a sea wave protective grid/lattice/shutter. Balance the boat with fuel seems a bit complicated for me. There is not much weight in fuel - I guess you have about 2x250 liter; in theory you can move max 250l x 0.75 = 180kg. (Same as two Stora Starka Norska Män on one side of the boat). Your sturdy boat should be just over 10 tons, so how much does it leans with 2 men - or 3 jenter - on the side? :-) Samt, återinför Kalmar Unionen! ❤ Regards, Martin
Thanks for you comment. It is interesting to see your solution of taking the fuel from the bottom. I can clearly see a benefit of that. Do you have a video showing this solution? Sounds like a great idea. Om our boat we remove some deciliters from the absolute bottom of the tank some times a year and then we know that it will not build up with water or nasty stuff. And regarding the Kalmar Union, we absolutely agree. That would be a very good solution. At this time, the current Union is the best we have (even if we are actually not in it), but in the future, when the world is no longer as it is today, the Kalmar Union might come back to live. And while we're waiting, let's do some sailing!
Hi, I am in the middle of doing a restoration on a Nauticat 44 for a long distance cruiser. The fuel system is something I intended to work on before splashing the boat again. The later models have a single lever valve under the after wheelhouse step so you can operate at sea without going into the engine room to take and return fuel from which tank you like. Also if a fire breaks out in the engine room, you put it in the middle and no fuel comes out of any tank to feed the fire. The plumbing is all in copper from the tanks. That valve is out there somewhere to do that already so might save some work. I can email a picture if you like. So I intend to only load fuel in one tank and run the engine from the other. Clean, treat and polish the new fuel in the loading tank until I'm happy with it then transfer to the engine tank using the unit below. I'm looking into a separate system called a diesel dripper. A bit like a mini system you would have on a commercial ship for cleaning the fuel. You can filter out water and polish the fuel when the engine is not running as it's separate from the engine system. My plan on extended cruising is to have it running on days the solar has the batteries at 100% at anchor and just keep the fuel moving and clean in one of the tanks Look up Marship diesel dripper, that's the way I'm going with mine. I was the man that asked about a video of the anchor clearing the bobstay when lowering. I went for a 45kg ultra in the end as it worked a little better for me with my deck setup. Have you still got the package glands on the rudder and drive shaft. I'm keeping mine as easily maintained in far of lands. The problem with them is I could never get a spanner/wrench to fit them correctly in the spare you have to work in but I have now found a company that makes very large spanners for the packaging glands out of stainless steel at a good price. I have four on order and we will see what they look like when they arrive.
Hi there. Thanks for your great comment. It sounds like a super solution with the single lever valve that does it all. Please do e-mail me information of that. I have added my e-mail in the contact section, so you can pick it up from there. (Does not work to put e-mail in this comment, YT will remove it). Tell me if you can not find it, and we will find another way. The fuel polishing I would also want, but I have not found the right way to do it yet. But it is absolutely on my list (that grows every day...) The 45 kg Ultra sounds like a beast, and I am sure you will be happy with that. Regarding the package glands, what is that?
Sorry Charlie I don't see the email address on my side of the screen. Google a "six port fuel valve" The packing gland is the part on the rudder post and drive shaft that keeps the sea water out. The water tight seal. The old type ones you put a type of rope into them and tighten to make a seal and the new ones have a rubber seal. I'm keeping my old type that has graphite rope so I can always work on it even mid ocean and stop it from leaking .
Good clear video. Fair wnds for 2025
Thanks a lot. Glad you liked it.

Let’s try to work around it. It is as follows: hello att jarlekarlsrud dot no
Ok hopefully that worked if I got it correct
That worked out just fine!

Thanks for this link. That is absolutely something I will invest in, for both my tanks.
