It is the round peg in a square hole that is pretty much worthless. (Never let a rocket scientist do your timber framing.)

But apparently diesel fuel has a boiling point way above that of water, so one can fill the tea kettle with watered fuel, boil off the water, and when the steam stops coming off, use the dewatered diesel for the engine. "Lather, rinse, and repeat."

Boiling off diesel fuel on the stove, what could possibly go wrong?
On a boat at sea to boot?

Ridiculous method. If you're willing to make clean diesel one teapot at a time, then just pour it off the top, and stop pouring when you get close to the watery dregs. Simples. Or better yet, just pump it or siphon it off the top of the main tank.

Boiling it will thoroughly mix and probably even emulsify the fuel and water. If this works at all (and I have some doubts), you would have to do it for a very long time, and you only get a teapot at a time.

Re: Bad Fuel Challenge

I was taught that to get oil and water to mix, you heat them up and add vibration.

Jerrycans are sealed, unlike the vented tank, so there is no opportunity to introduce more air/water vapour into the system. In addition they can be kept completely full leaving little air space.

If the fuel that is put into the jerrycan contains no water none will develop.

Filling the jerrycan from a different source to the fuel in main tank provides a further degree of independence.

As a side issue why do manufactures put fuel filler caps in areas that are exposed to water

Re: Bad Fuel Challenge

While it is an interesting concept, there are several courses you could take to address the challenge. #1) Do not put yourself in this position in the first place, that starts with pre-voyage planning. 2#) Use the hose to siphon the water from the fuel tank, ( if possible), clean everything up and start again. #3) Siphon fuel into the 5 gallon jug and place the pick up where it will not take up the water in the bottom of the jug, run your return line back into the same jug. Again, clean everything out and restart. If you can get the engine running long enough to charge your batteries then do so and it will prove the engine can be reliable enough to shut down again, and will restart. Continue sailing into shore where ever, sip the Jack while contemplating the beauty of the ocean. Upon arrival if engine does not start, I would take the vessel in tow with the dingy only not on the hip, I would save that until just prior to arriving at the slip. I would just tow the vessel astern until inside protected waters, then hip up. Though no one has mentioned this, if you are able to allow your powered vessel's stern to extend past the stern of the hipped up vessel, you will have greater maneuverability and control.

Re: Bad Fuel Challenge

what we did to leapfrog into zihuatenejo was place all remaining fuel into a pail with known quantity as capacity. we used this pail as the main fuel tank and judged accordingly the distance vs quantity remaining. lol was a fun time. we made it just perfect.

when i had what we thought was dirty fuel vs water in line we used a jerry jug for the fuel pick up and return lines and went thataway fro a day or two until we learned it was shape of fuel pick up coming from top of tank..lol needed to be redesigned. we did that. then we made a pick up in bottom of tank, where they belong.....all of these except the pail were done more than 18 miles from port.....the pail was done that way after a couplafew days of drifting off ixtapa, less than 4 miles off coast....
a hot shower at my friends house in zihuatenejo looked too good to continue to drift..lol

there are many ways to fix the problem of finding a problem within thought of the unlimited water hot shower, or the beer, or the wtf you have waiting on the beach....

Re: Bad Fuel Challenge

with regard to the event this is based on - sorry but, seems to me a case of abandon ship because we've run out of electricity. its a bloody sailboat. sails, wind. Motors are generally referred to as 'auxiliary', electrical equipment is or should be irrelevant to sailing the boat. Something to be said for learning how to sail on small boats, at least you learn the basics.

On the other hand it is interesting in how paranoid some seem to now be getting. I had my engine shutdown this year from a fouled filtered. It hasn't made me do anything other than to remember to check the filter bowl when checking other things on the engine.

This is sailing, chill out a little!

On the plus side, have my 4th person to put on the list.
If the question is how to clean up your fuel on a sailboat so you can start your engine and not have to abandon ship 20 miles offshore the next logical question to ask is 'say what?' After all, it is a sailboat and the engine should be an optional extra.

If the problem to solve is more along the lines of you want to start your engine to generate 120 vac so the blender will crush more ice for Margueritas, then the siphon the water out of the tank if you can, siphon fuel into a bucket, then empty that into a few garbage bags holding clean fuel into which you put your suction hose could work.

Better yet, is actually to prepare for bad fuel when re-fueling by starting first by filling a glass quart. Leave it be for a couple of minutes, then inspect. If it looks clean, it is clean enough and fill away. If the fuel is not clean, you'll see it in the quart before you fill your tanks with it.

First question: Was that 'preachy?'
Second question: Do these pants make my butt look big?

Re: Bad Fuel Challenge

The diversity of opinions expressed in this thread illustrates the value of these discussions, they get you thinking about things you may not consider until you are actually in trouble out there.

Regarding the subject of clan fuel at source.

When you long distance cruise you often are obliged to take fuel wherever you can find it and don't have much choice regarding it's quality.

My own discovery of the need to have a fuel cleaning system was not a particularly enjoyable experience. Had the dirty fuel problem and consequent engine deprivation occurred whilst I was far offshore in deep water I would not have been too worried. Unfortunately it never happened that way, it just about always occurred after a long day of rough downwind sailing where the wind is off the stern quarter and really throwing the boat about.

The really heart stopping experience is when you commit to an entry, start the engine and it runs just long enough to get you into a position where you are obliged to stay committed and cannot turn around and go back to sea. This is when your roller furled genoa really comes into it's own.

There is a fairly simple solution to the water problem which allows you to get by until you can take action to remove the water from the tank and that is to either have a high and a low outlet or have an adjustable stand pipe if you fuel off draw comes from the top of the tank. Run normally from the low offtake and if you begin to have a problem with water change to the high or raise the standpipe. There is no solution to the gunk problem except getting it out of the fuel.

Before I installed the spaghetti jar water/gunk separator I used to remove the gunk by pumping the fuel from the tank with an impeller pump and returning it into the fuel filler through a long skinny, polyester sock sewn up from a felt like cloth. When the contamination was bad I would have to stop fairly often and empty the gunk into a bucket which was easily done by turning the sock inside out. The sock is now inside the spaghetti jar.

Oh pish, that's only an excuse for the poor folk. Most of us just have sealed jerry cans shipped ahead by Fedex or DHL. Then the empty fuel cans can be sold to the locals, often at a good profit.
Buying fuel locally. Really now, that's almost as risky as drinking their water. And if you're finding their water in their fuel, lord only knows where else it has been.

Re: Bad Fuel Challenge

Hi helosailor, you must be a multihuller and consequently accustomed to boundless extravagance, two hulls, two engines, pedigree pussy cat, 10,000 gal/day watermaker, fancy woman, etc.

Us poor old monohullers certainly can't afford fuel made from food grade olive oil and shipped in monogrammed, stainless steel containers express post, special delivery DHL or Fedex.

And yes, having only one, poke-along-steady hull rather than two skinny, blaze along, laid up by blonde cheerleader hulls obliges one to drink the local water along with buying their fuel.

I can live with this but what gets my goat is that I just know that whilst I am down on the beach drinking yeasty home brew beer with the guy who sold me the fuel and so kindly allowed me to fill my salvaged orange juice container, water container from his cholera riddled, sewage infested, backyard well, you are up at the bar drinking $40 a pop cuber libre's with your multihull mates and bragging about the fact that your million dollar, two hulled, gin palace only draws 12" of water whilst us ballasted monohullers are going aground on every low tide because you are anchored in the only deep water in the anchorage with 150 yards of gold plated, SS anchor chain out.

Of course the water in the fuel came out of the sewage riddled, cholera infested well, with waterside real estate costing what it does and all the bribes and land taxes a businessman has to pay these days one has to make an extra buck somehow.
