Fuel Polishing

http://forum.ssca.org/phpBB3/viewtopic.php?f=4&t=7697

OK its a bunch of rag baggers , but at least there out away from the power pole.

In this discussion the "pro" discussed cleaning the fuel and the tank , as opposed to sipping a bit of fuel and cleaning it* "fuel polishing"..

Very different concepts and very different equipment .

RE: Fuel Polishing

OK, OK.* Decided today to have a fuel polishing system installed on my Coot.* That with dual Racor filters will hopefully avoid most fuel-quality problems.* * (Geez, how many valves will there be in the engine room?* They better be well-labeled!)



(Ignore the genset.* I'm not having one.)

Fuel Polishing

Mark , if you change the design around a bit you only need one set of Racors, the filters should be before the pump to protect it and the fuel pump can prime the engines.* I will see if I can post a diagram of my fuel polishing or send me*your email address and I will send to you.**

When we got the Eagle into her permentant*slip*I shut down the engine, sat in the engine over whelmed with all the*valve and stuff.* I left the boat and did not return for several weeks.* *****

RE: Fuel Polishing

Geez P/F, if you can't read a drawing how can you expect to provide one for someone else?

How's the charter business going?

Rick, why exactly do you keep picking at Phill Fill every chance you've got? This is starting to be really annoying and totally out of place. I wish the moderators would play their role here...

RE: Fuel Polishing

Here's a link to an article about fuel polishing that was on the Trawlers and Trawlering site written by Will Andrews. Hope this helps. http://www.sentoa.org/maintenance_ti...polishing.html

Mark, do you have 120vac in the ER?* Your fuel capacity is around 400 gallons?

RE: Fuel Polishing

Save your money.

I had my 400 gallon tanks polished by an outside firm and we found less than 3 oz of asphalt in the tanks after 5 years.

The tech said he hated to take my money and to keep on doing what I have always done; use Biobor religiously.

You've got a brand new boat mark. You can put that stuff on later * *...several years.


Just make sure you can drain or otherwise remove water regularly from the tanks.

RE: Fuel Polishing

Eric is absolutely right. If you desire, a 3 stage filter setup (similar to Jay Leonard's who has posted pictures) will eliminate fuel problems you will see for the rest of your life, unless you fill up with junk fuel of course.

RE: Fuel Polishing

Mark why no genset?* Just curious, not trying to debate.

When we were having all the problems on the sailboat with the gunked up fuel one of our dock friends who is a mechanic (albeit AUTO) swore by running off of a day tank of polished fuel. ... comments?

RE: Fuel Polishing

Jennifer, Like you, I'm a little surprised that there isn't more support for fuel polishing.* I'm sure that if you ran through your fuel quickly there isn't much of a problem, but I don't know of a manufacturer of a trawler that doesn't recommend the ability to remove the natural amount of contaminants that precipitate out of, or grow in diesel fuel stored for a few months, or longer.* Based on the crud I get out of essentially brand new tanks after a season of polishing the fuel before transferring it to a day tank, I'm glad I have that capability, so I'm with your mechanic.* Maybe it's a case of if you don't have it, you don't notice the absence.* Until you do, then it's a bit late.

Very expensive.
Crowds the engine room.
Don't have air conditioning.
Stove is propane.
Few nights not at a marina,*and not staying at one anchorage for long.
Noise.

I have nightmare visions of fuel blockage while running a bar at a bay's/river's entrance.

The idea is to avoid a build up of crud rather than waiting for it to bite my xxx.

While any filtration is good - however I can not see a normal fuel supply line providing enough flow to create the velocity*to distrub any crud that may rest on the bottom of the tank. The return line has to be able to not only have the velocity but also reach behind baffles.

We see large yachts that have very elaborate polishing systems (more money invested in the systems than what I paid for my boat) and they still have issues.

To avoid that fuel line blockage during a*bar/river entrance, this is where a day tank could be augmented with your polishing system.

RE: Fuel Polishing

Mark will you have an inverter?* We got a little one that plugs into a 12v socket and we can run our computer or TV off it.* We have a 4kw genset that we used at Angel Island (three nights over Thanksgiving) to run the stove*and charge the batteries.* The diesel heater won't start unless the batteries are near full charge.* Luckily we figured that out as we thought the heater had croaked!

Anyway I look forward to hearing what you decide to go with on your fuel polishing system and even MORE forward to hearing how well it is working when you get your boat in a few months!!* Seeing the hull painted makes it seem that much closer to COMPLETE!

Yes, yes.* DC system is 24 volt.Just my opinion, but a less expensive option that probably has some advantages is a system that has somewhat higher flow and a 2 micron filter.* The reason I prefer this is that when the tank is near empty and sloshing around, if you can filter it multiple times you really clean the tanks each time you run low on fuel.* The flow of a Racor type 900 is around 2 times greater than the Gulf you show, meaning you'd run the fuel through the filter 2 times at 2 mics for each time it passed once through the Gulf.* Your choice, and I'm not sure if your Gulf motor/pump combo (the one you show is for 300 gallons or less) will cost you the list of but here is a cheaper system that sure works for me:

1. Racor (type) Griffin filter http://www.amazon.com/RACOR-900FH-EQ.../dp/B002QO7S5I $145.00.
2. 1/4 hp 120 vac carbonator mount motor http://www.grainger.com/Grainger/MAR...458?Pid=search $126.00
3. ProCon rotary vane pump http://www.grainger.com/Grainger/PRO...E83?Pid=search $125.00.

You can add a timer if you like, but this might save you some $ and will certainly keep the fuel clean.* The motor is dead quiet, by the way.

I'm concerned that movements of the boat created by the water's waves will disturb that "stuff" and not the mere sucking of the fuel line.

Eight KW toroidal isolation transformer.
Dual 24 volt 200AH AGM house batteries.
Shore power system with CB protection.
Shore power volt meter.
24 volt inverter/charger.

There is also 120-volt AC wiring and sockets.

I'm not sure what all that means, but I expect to be able to charge the batteries and run a small electric heater when plugged in at a marina.
