Mostly water. ?- How?d all that get in there anyhow? === Yes, that needs to be understood, otherwise it will happen again. It sounds like it was a lot more than just condensation or ethanol phase separation. It could have been a bad fuel purchase, sometimes happens. More often it's from a leak around the tank fill, possibly correctable with a new O-ring. We had something a little more exotic on our last Caribbean trip - lots of symptoms of something going on, but no show stoppers thanks to a good set of large Racor water separators. It was getting worse however so needed to be solved. After doing a number of thought experiments I figured out that it was likely the fuel cooler on the return flow to the tank, something unique to large diesels. We had a mechanic in the BVI pressure test the cooler and that turned out to be the problem. Blind pig finds acorn on first try. :-) We still had a lot of water in the port side tank however so had to pay a fuel polishing service in St Martin to run it through a big centrifuge: Lots of $$$ for that and about 40 gallons of discarded fuel/water mixture. --- This email has been checked for viruses by AVG. http://www.avg.com The fuel fill is raised a little above the deck, so maybe slowed down water intrusion. I replaced the tank in about 2002. Had a corrosion hole in the top. Maybe I need to pull the deck and see if there is a hole. Deck is screwed down covered plywood. So not a big problem to pull. === Good plan. |
