Re: Stus-List Fuel contamination

[Della Barba, Joe via CnC-List]

We just went through this on a friend's boat. The boat was abandoned for years 
and in the end we had to replace the fuel tank.
Some things to keep in mind:
1. A professional fuel polisher set up, either installed onboard or used a fuel 
cleaning service, has much higher pressure and volume than you will get by 
using the lift pump to recirculate the fuel.
2. If the pickup tube has a screen, you will go nuts with random pieces of crap 
clogging it and then falling off later.
3. Vacuum gauges on *each side* of the Racor are vital to determine if the tank 
pickup is clogged or the filter is clogged.
4. If there is a way to remove the fuel tank, do so. I cleaned mine out with my 
garden hose and soap at home, but only them realized there was no drain at a 
corner to get all the water out. My wife thought it was funny watching me jump 
around in the yard with the tank over my head getting the last of the water 
out. That was followed by a couple of methanol rinses to have a perfectly clean 
and dry tank. YMMV on how to do this, but you need to see into the tank.
5. 5 year old fuel - yikes! Get rid of it.

Ps - vacuum gauges are all over Fleabay for good prices. The liquid filled ones 
only work right if they are vertical and you CUT THE RUBBER PLUG to create a 
vent. If you don't, the readings will be wrong - sometimes way wrong. Don’t ask 
how I know this..

Re: Stus-List Fuel contamination

[Marek Dziedzic via CnC-List]

The problems with fuel might be many, but they fall into a few simple
categories:
 - water in the fuel (the worst kind, because it encourages the grows of
algae)
 - debris in the fuel (should filter out, but if you have plenty of that
stuff, the filters might get clogged)
 - mechanical problems with your fuel system (leaks, air leaks, pumps,
filters etc.) - but polishing fuel won't help here.

If you have no water in the fuel, there won't be any algae growth. The gooey
substance that started this discussion is the algae that growth in the fuel
tank (and eats the fuel), but it grows in the water.

Who knows what might be luring in your fuel tank, but the fact that the fuel
is 5 years old does not mean that it is necessarily bad. Use it up or, if
you have that option, pump it out and give it to the yard's tractor driver.
Obviously, newer fuel is better, but if your engine was running for a few
hours, your old fuel is not that bad.

When I bought my current boat, it had an almost full tank and the fuel was
already about 2 years old. I used it for the next two years without any
incident.

Change your fuel filters often enough (as per the normal maintenance
schedule), buy the new fuel from reputable places and don't worry too much.

Two filters (the primary 30 um and the final 2 um) should do the job.

Re: Stus-List Fuel contamination

[Josh Muckley via CnC-List]

I like this idea Doug.  It is similar to one that I have had but not
implemented.  I do have a small 12v fuel pump and have used it to "turn
over"  the fuel.  I ran hose from the outlet of the racor to the pump and
then hose out the window to the fuel fill port on deck.  Used and "filter
funnel" at the fill port to try and scrub water from the fuel.  When I was
done I changed the racor.  In theory I'd like to do this annually as part
of the end of season maintenance.  Since i have not had trouble and did not
have any surprises with the filter funnel it has become low priority and
perceived as overkill.

Re: Stus-List Fuel contamination

[Douglas Mountjoy via CnC-List]

I would carry extra filters, and fill with fresh fuel.
Pegasus sat for a couple of years when I bought her. I didn't have any
issues with the fuel until I got into rough water, and stired up the fuel.
Now I change the filters once a year and have no issues.

Re: Stus-List Fuel contamination

On Pegasus I have a system that alows me to pump fuel through my filters, 
then back to the tank. Not sure I would call it a fuel polisher. I put it in 
after spending a hour trying to bleed the filters while under way. I have a 
valve before the engine andafter the filters, and one that allows fuel to 
return to the tank. For pumping I installed a small electric pump. I also 
installed a canister Racor filter after the Racor 500. The 500 is 30micron and 
the other is 2micron. If you want a picture or more information email me, to

Hi this issue is a concern for me as well.  Now, on the boat we're buying, we

Re: Stus-List fuel contamination continued-jelly in the filter

[Paul Baker via CnC-List]

I had the same problem with mine, bowl full of jelly and the only quote I could 
get for polishing and cleaning the tank was well in excess of the new tank 
cost.  I ended up replacing the original 40gallon metal tank with a 10gallon 
plastic one as there was no way I would ever get through 40gallons in a 1GM10, 
little bit of cutting and some mounting bits and it was all done.  Not a 
difficult job assuming you can get the old tank out.
