as an owner of a very expensive new hatch cut in the deck some words of advice/ experience.

i broke down in 2008 and was advised it was "THE BUG" did the diesel maintenance course, replaced filters frequently normally if there was a saturday in the month, and religously treated all incoming fuel with an additive - marine 16 which i think was the pbo winner of a test.

 

i also had the fuel polished after the initial problem and whilst not present while it was done a berth neighbour saw a load of gunk coming out and being taken away. all well and good

 

fast forward to 2011 and breakdowns again. in short the bottom of the tank (we eventually stuck a camera down) was covered in sand / rice like particles which when disturbed were not blocking the filters- as bug is supposed to, but were blocking the pipes and junctions in the filter body itself, the reason why when i changed the filter cartridge with the spares carried the problem was not solved.

 

i will never no where/ when this came from or why but it does mean that if you do go the polishing route you have to make sure you get to the bottom of the tank- and mine has three bafffles which presumably meant that the original polishing company had no chance of doing that as the only access then was thro the fuel sender access

 

polish yes but it does not gaurentee problem free boating

 

oh and i am now very familar with stripping down the off engine fuel system at sea!

ps when we cut into the tank and removed the remaining fuel it was polished, when it went back in after the tank was cleaned, it was done again. i shall be mighty peeved if this happens again!
