Fuel polishing filter
 
I'm setting up a fuel polishing system.

And would like a easy to find & cheap filter system.

Will circulate approx 1.5 gpm.

Any suggestions?

Yeah I know he put in a system for his trawler.
I was hoping he would have a suggestion. I have a fram housing...
checking on the cost for elements, also have a Racor but it is a bit to
expensive, 11 dollars per filter element. I also have a fine stainless
steel reusable scrubbale mesh filter I will use a a pre filter.

Also putting a water trap inline. It would be noce to have a big screw
on fuel filter that was reletive cheap to replace,

So fine you can barely blow air thru it

Ive heard of systems using paper towel rolls

What is that in microns?

yeah, I've also heard that bits of paper towel can end up in
your fuel.

Actually, I have not put in a polishing system (yet) but
just rebuilt the fuel system and filters.

Which one? We started out with the 900FG (in fact I still
have it) which IIRC the elements were about that. But it's
designed for a 90gph engine, whereas ours is only going to
demand 1/20th of that at full throttle.

I put in a twin mount 50 gph Racor and use 2 micron
elements. It has a very good water seperator, the elements
can be changed without spilling fuel, and if you buy them by
the case are about $4 each.

IIRC stainless and diesel don't play well together. And a
screen is not a filter, unless you have marbles in your fuel ;)

IMHO a screw on filter is a mistake. Guaranteed to spill
fuel, often leak, more expensive because you have to buy the
whole housing with every element.

If you want "cheap" use one of those toilet paper roll
filters. But hey, which is more expensive... a couple cases
of good filter elements, or a new injector pump?

Re-piped ? Is your hard piped? What kind of tanks & capacity?

You might have a problem with it, if it has a water seperator at the
bottom of the housing you need the 90gph flow for the seperator to work
properly.

The price is right, I'm assuming the twin mount is in line to your
engine and not for a polishing system. I use a vaccume gauge in-line to
avoid shutting down. I should go to a dual system, sure is nice in a
bind to just switch and deal with the filter later.

It's a very well designed primary for diesel, the mesh is finer than
flame screen, stops any alge.

Probly right, Most likely going to stick with the tried and true
Racor, despite all the gaskets hassles.

filters. But hey, which is more expensive... a couple cases

My main and gen have a racor, then 2 secondary filters on the main and
one on the genset.

I've only heard of paper towel and TP filters but have never seen one,
better than nothing in some third world **** hole were filters may not
be found.

Smart thing to do is invest in many filters before kicking off.

A smarter thing to do is have a *sailboat* without a motor. I know why you guys don't sail very much.
It's because you spend half of your time getting cozy your motors. Then you spend the other half of your time
talking about how you get cozy with your motors. Duh! Then you go broke buying stuff for them.
Back yard mechanics is all you are. You wouldn't be happy just sailing.
In general, men are so clueless. Always putting on some kinda act. Sailors don't have black fingernails.
Men with black grease under their nails are pretty gross. No offense, Joe. I think your a sailor at heart but
you just got off track somehow.
Joe's problem's like most other people who live aboard their sailboats. The get them way big for the space
for all their boat things. Then they fill them up again with everything you'd find in an apartment. Then they
have to have a motor because their boats are so big and heavy and low in the water the sails hardly work.
Then their motor becomes the centerpiece of their boats and their lives. They worship at the internal combustion
altar. The sails are all but forgotten. Why bother when it takes 30mph of wind to make the boat go using them?
In another post somebody said forty feet's as small as he'd want to live in. Duh! Maybe admit to yourself
you don't want to sail. You want to live in a house that floats but never goes anywhere using the sails. Make
yourself happier. Get a motorboat. At least then you don't have to pretend your a sailor.


Cheers,
Ellen

New lines (industrial (ie not refrigeration) 3/8" copper
tubing (which is overkill, but it's easier to work with & I
like it), new valves, a new manifold, plus the new filter
housing.



Which one? We started out with the 900FG (in fact I still
have it) which IIRC the elements were about that. But it's
designed for a 90gph engine, whereas ours is only going to
demand 1/20th of that at full throttle.



You might have a problem with it, if it has a water seperator at the
bottom of the housing you need the 90gph flow for the seperator to work
properly.


Well, you at least need a high percentage of that 90 gph for
the turbine to get any centrifugal action. OTOH, the bowl is
large enough that at very low flow, the water will just
settle out. The ones we use, 50 gph rating, also have a
large bowl and the centrifugal element should work at much
lower flow rates.

The real answer is, I don't know, I have only seen a very
small amount of water in the seperator once.


The price is right, I'm assuming the twin mount is in line to your
engine and not for a polishing system.


Currently, yes. When I put in a polishing system, it will be
a pressure feed system using the same filter/seperator
though. I will only use it when the engine is off line.

One important point I just learned: in a polishing system,
the return should be to the bottom of the tank. If it spills
in at the top, it does not scour the bottom of the tank
sufficiently and there will still be pockets of crud.


I use a vaccume gauge in-line to
avoid shutting down. I should go to a dual system, sure is nice in a
bind to just switch and deal with the filter later.


Yes, very much so.



My main and gen have a racor, then 2 secondary filters on the main and
one on the genset.


Same here. The genset isn't bad, but the s
filters on our engine are guaranteed to spill fuel and are a
PITA to get to when the engine is hot. I change them once a
year whether they need it or not, the benefit of using 2m
filter elements.


I've only heard of paper towel and TP filters but have never seen one,
better than nothing in some third world **** hole were filters may not
be found.

Yep. Any time I have less than a dozen on hand, I feel a
little nervous. And they're cheaper by the case.

As for paper towel & TP filters, it seems likely to me that
you would end up with paper going into the engine,
especially if they took a slug of water. They may trap lots
of little particles, but then, with no structural
reinforcing to the filter media, what keeps it from flexing
and letting them all go again?

And I can say definitely that their claims of use on
military & gov't vessels is bordering on fraud. NAVSEA would
make a dartboard out of the balls of any engineering CPO who
put in such a system without authorization.
