monkeyhanger Posted May 14, 2013 Report Share Posted May 14, 2013 Last summer I had problems with blocked fuel filters which I'm pretty certain was diesel bug. I sorted it by changing filters and giving the tank a hefty dose of Marine 16. I'm about to set off on a 3 month summer cruise, part of which will be on rivers and , obviously, I don't want to encounter similar problems to those I had last year. I am considering having the diesel in my tank"polished", i.e. filtered and returned to the tank, somewhere along the route of my journey. I intend to go London-GU-Braunston-Warwick-Stratford-Avon Ring-Birmingham-Coventry Canal- Braunston-London. Can anyone recommend any Fuel polishers on that route, or should I just dose again with Marine 16? I have at the moment 100 gallons of diesel in my tank. Any thoughts/suggestions much appreciated.

monkeyhanger Posted May 14, 2013 Author Report Share Posted May 14, 2013 Calcutt boats do fuel polishing Any idea how much? Have you any experience of their work? Link to comment Share on other sites More sharing options...
churchward Posted May 14, 2013 Report Share Posted May 14, 2013 Calcutt boats do fuel polishing They also do fuel polishing at the bottom lock on the Braunston flight. Link to comment Share on other sites More sharing options...
magnetman Posted May 14, 2013 Report Share Posted May 14, 2013 iirc forum member Bones had fuel polishing carried out a while ago and there was a canal boat mag article about it. Link to comment Share on other sites More sharing options...
onionbargee Posted May 14, 2013 Report Share Posted May 14, 2013 the usual fuel tank built into the stern is a poor design usually without adequate drain off, time to get builders to up their game, an insulated (to stop condensation), v bottomed stainless tank with drain would be better. No need to ever polish then. 1 Link to comment Share on other sites More sharing options...
PhilR Posted May 14, 2013 Report Share Posted May 14, 2013 the usual fuel tank built into the stern is a poor design usually without adequate drain off, time to get builders to up their game, an insulated (to stop condensation), v bottomed stainless tank with drain would be better. No need to ever polish then. Any insulation inside the tank might fall off and block the fuel lines? I reckon an aglomerator and/or sedimenter are essential and should be regularly checked for water and sediment. I'm sure a few people on this forum have bought contaminated fuel at some time.

comfortably numb Posted May 15, 2013 Report Share Posted May 15, 2013 I was told on an RCR couse recently that you should expect to pay between £100 & £130. It's something I am considering having done with my recently bought boat and then I plan to fit a sedimentor and/or aglomenter thingy. Expensive precautions I know but IMO well worth it if it helps prevent problems in future. Link to comment Share on other sites More sharing options...

PhilR Posted May 15, 2013 Report Share Posted May 15, 2013 Insulation INSIDE !! you are having me on ? Yes. Sorry. But seriously, it is probably not possible to fully insulate an integral tank and I can't imagine freestanding tanks being popular. Link to comment Share on other sites More sharing options...
MtB Posted May 15, 2013 Report Share Posted May 15, 2013 Is 'fuel polishing' the correct process for removing residual canal water, rust and general crud from inside the fuel tanks on REGINALD, or would physical tank cleaning following fitting of some access panels be more appropriate?

magnetman Posted May 15, 2013 Report Share Posted May 15, 2013 I think the latter myself. cut a hole in it, have a good look inside, clean it then weld or possibly drill tap machine screws to fix a plate over the hole. Link to comment Share on other sites More sharing options...

I used GUDS last year and can recommend them. The charge was £95 if I recall correctly. They also put a camera inside the tank so you can see a 'before and after' picture.

J R Posted May 15, 2013 Report Share Posted May 15, 2013 Prevention is often better than a cure. Use an oil extractor pump (Pela pump) each year with the plastic tube taped to a length of wood to dip into the tank and suck out any water or c**p that is in the bottom of the tank. Has done the job to date. On my boat the fuel takeoff is a couple of inches above the bottom of the tank so all water and crud is, in theory, not sucked into the engine. Also have an inline water seperator plus a seperate filter as a precaution. Link to comment Share on other sites More sharing options...
MtB Posted May 15, 2013 Report Share Posted May 15, 2013 All the fault of the integral mild steel stern tank on Narrowboats. Not fit for purpose. Not necessarily. REGINALD has two removable saddle tanks under the floor either side of the engine, suspected contaminated with canal water from when he sank.

I sorted it by changing filters and giving the tank a hefty dose of Marine 16. That doesn't sound right to me. From experience, if you have diesel bug you will have a lot more that a blocked filter. The bug looks like someone has dumped a load of butter in your fuel system. It blocks everything. Fuel polishing is not what you are looking for. Polishing cleans contaminated fuel. If your engine/heating are working fine then you don't have diesel bug. What you probably do have is water and dirt in the bottom of your tank, which is a perfect breeding ground for bug. You want someone to suck all of that out. That process is not difficult, you just need a pump and a rigid tube. Link to comment Share on other sites More sharing options...
john6767 Posted May 16, 2013 Report Share Posted May 16, 2013 Based on the discussions on here last year I swapped from using Fuel Set to Marine 16. Previously as expected I had never had an significant amount of water in the bottom of the fuel tank when sucking it out with a hand pump. This year I got out over a litre of water before it started coming out pure diesel. So I guess that does prove that Marine 16 does work as expected and differently to Fuel Set, but I don't really like the ides that by using Marine 16 you are purposefully encouraging water to form at the bottom of the tank.

WJM Posted May 16, 2013 Report Share Posted May 16, 2013 Where would you rather have it considering its in the tank somewhere? If you have water in your diesel tank then the best place to have it is emulsified within the fuel - and not sitting separately on the bottom. Diesel bug lives at the interface or oil and water, so the best prevention is to destroy that interface. Based on the discussions on here last year I swapped from using Fuel Set to Marine 16. Previously as expected I had never had an significant amount of water in the bottom of the fuel tank when sucking it out with a hand pump. This year I got out over a litre of water before it started coming out pure diesel. So I guess that does prove that Marine 16 does work as expected and differently to Fuel Set, but I don't really like the ides that by using Marine 16 you are purposefully encouraging water to form at the bottom of the tank. So what you are saying is: Using Marine-16 you are now getting clear water at the bottom of the tank, whereas when you used Fuelset that did not occur? I am currently dosing with both.
