Re: Accidentally put water in diesel tank ...

Unless agitated...just pump/drain the water off...any diesel tank without a bottom drain is useless no matter WHAT ANY safety organization has to say.

The trick is to get ALL the water out...any water does the engine, leftover fuel and tank no good.

DON'T use any additives to get the water out...you don't want to suspend water in the fuel...NOT recommended by many engine manufacturers. Alcohol is only OK if you wind up getting rid of the entire tankload so why add the alcohol to begin with?

If you feel like you got all but a tiny bit of water out...then agitate the crap out of your tank and burn up a lot of fuel...in other words take a nice sea run with plenty of water separating filters and Sea Tow!!!

Most of the stuff posted here make me cringe...ask a good diesel mechanic or post somewhere sailors are the minimum...like a trawler forum where the diesel is their lifeblood...sailors might be informative about sails but so far many are way off base on diesels and the fuel (some are dead on but hard to pick out).

Re: Accidentally put water in diesel tank ...

Been there done that. I asked my son to fill the water tanks and he filled the diesel tank with water. I couldn't figure out why the generator wouldn't start. checked the water separator and it looked like diesel. I spent half the night pulling the diesel from my tank and transferring it to Jerri jugs and then carting it up the dock to the oil dump. This was in Mexico. I am sure it would have cost me a fortune to dispose of the same mess in California and what I had done was probably illegal. Another option that you have is to get a fuel pump and suck all of the liquid out of the tank and put it into a jerri can passing it thru one of those funnels that removes water WEST MARINE 006_180_003_517 at West Marine I have done this before and it works pretty well. You still have a filter water separator before the fuel goes into the engine. You'll have to watch that closely.

After-action report, if anyone is interested:

Thanks to all for advice on my original inquiry. I also contacted a local Miami fuel polishing service (Diamond Diesel), who offered to come out anytime on emergency. However It didn't appear that polishing was necessary. It's kind of a pricey service due to the cost of the equipment - for a small vessel it may be cheaper to replace the fuel if you can't polish it yourself.

I inserted a stiff tube through the tank indicator opening and pumped out about 20 or more gallons of water, moving the tube around as best as I could reach, until pure fuel showed. I have run the engine about three times since then with no problems apparent, each time for more than an hour at speed. After each running I drained the water separator, removing less and less water each time (no more than 3-4 oz last time). The tank is now full of fresh fuel with additive and biocide, and I will continue to watch the Racor.

Agreed. I don't think I've ever seen this amount of misinformation in a CF thread. Good for the OP for sifting through it all.
