Good queries - mirroring my own

Re > Should the element/filter (I assume it's the same thing) be 2, 10
or 30 microns?

You need to find out how many microns your original filter works to -
think between 5 and 10 microns - I checked a filter that I have in the
vehicle and it doesn't say it on the side or box.

Is there a point in pre filtering to a micron level smaller than the
second filter? - if you do then the second filter has no work to do - as
the pre-filter has all the work done.

Re water removal - not sure that any filter will remove water.

As far as I know the filter assembly/housing "settles" the water out....


Cheers

Niall

PS - Was onto Felton also - they must be wondering why there is such a
rush on Racor filters :)

Re> They quoted =A3120 plus VAT for a 500FG. Have you had any better?

Best I've got so far is =A3156 +VAT for a volvo version with a steel - as opposed to glass bowl

Re the term "settles out" - begs the question of whether the bigger filters "settle" out more water than the smaller ones - ie the 900FG model

Cheers

Peter,
I normally buy the brown (30 micron) and blue (10 micron) elements.
Never used the red yet (2 micron). While in Europe I use the brown
element, and elsewhere the blue one. I'd suggest taking with you one
or two OEM elements. You can buy them from Toyota dealers in major
towns and they will be probably cheaper than here. Small shops will
sell them too, only their origin will be rather dubious. As for Racor
elements, take as many as you can, because they are unlikely to be
available locally. Perhaps one element each 30 - 45 days is a
reasonable guess.

Water will pass through a 1 micron filter =96 at a guess water molecules are a
lot smaller the hydrocarbon chains that make up fuels.

Usually the fuel flow if used to set up a swirling flow that forces the
heavier water molecules out to the edges, the filtered fuel in taken from
the centre. The water collects together and settles at the bottom of the
filter bowl. Larger bowls allow more water to be held without the water
getting back into the fuel but if you have a lot of water just drain it down
regularly.

Subject: [ELCO] Overlanding Queries Racor Filter - More Advice!

I've found another Racor supplier who seem to be very much on the ball
HYPERLINK "http://www.asap-supplies.com"www.asap-supplies.com and whilst
ordering I was stumped by a question about microns. Should the
element/filter (I assume it's the same thing) be 2, 10 or 30 microns? My
initial reaction was to go for 2, but this would leave the second filter
doing very little. What about 10, the half way house? Which ever one it is
will remove the water, so I suppose it could be 30!! Doh!!

Isn=92t google amazing (and distracting, liable to side track you and cause
you to read all sorts of weird information)
For H2O, the H-O-H bond angle is about 104.5 degrees and the H--O bond
distance is about 1.0 Angstroms (100 picometers =3D 100pm). Wikipedia said
95.84pm
1000000 picometers is 1 micron, water molecule is 0.0001 micron!

Hi Peter,
throw away the factory filter you are just uneccessarily creating a flow
restriction just use a 2 micron filter in the 900FG ( or even a 1000Fg
if you find one on ebay or similar going cheap). elements will last much
longer than factory due to the centrifugal style of dirt removal in the
filter housing. elements are very light so if you took 6-10 that would
probably last 5-10++ years of running on good fuel.

Morning Peter,
I can't remember if you can see the filter in the bowl, the bowl
provides a good indication of fuel quality and water content - I seem
to recall the water builds up in the bottom.
As for knowing when the filter needs changing - basically as you
suspect you will notice a loss of power as the engine suffers from fuel
starvation.
You can pre-empt this by changing the filter regularly, although every
change may not be necessary.

Have you sorted a location to fit the filter housing.

Just looking at my machine - there's just about enough space space but
it may impede the access to the oil filter.....

+ actually being able to see into the glass bowl could be difficult...

Cheers

Keep me posted as to what your at.

RE > I'm thinking of taking the OEM filter out and relying only on the
Racor.

I wonder if the Racor that much better?

A positive aspect of the OME one is that it has a water sensor rigged
into your dash warning lights...

Saying that, the Racor is renouned for water seperating ability.

Keep it lit

On commercial applications we measure pressure differential across the
filter and look for an increase in the pressure difference to signal a
filter change =96 same technique on oil filters.

Perhaps a bit clever for a LC, perhaps a bit clever for anything, I spent an
hour tracking down the reason why a new engine (fully electronic 2000bhp+)
wouldn=92t start only to find someone had connected the sensors the wrong way
around, 2 minutes to diagnose with the laptop plugged, an hour and a diesel
bath without.

LAST query on this subject .. and thanks for your help to date .. How will I
know that the filter needs changing?

Peter,
Most of the guys I know (French, Germans) whom I have met in N Africa
use a dual filter setup. Craig's advice seem to be valid for Oz and NZ
where the quality of fuel is likely be better by a few degrees of
magnitude.
To give you an idea what to expect in Africa, have a look at this hand
operated pump in Chinguetti and imagine what sort of stuff comes from
the underground tank, filled with brackish water, sand, rust flakes,
used engine oil, goat urine and also diesel fuel for a good measure:

I am quite sure the 500 series offers good filtration and is big
enough, yet can be easily fitted under the bonnet.
Links to the fitting pics have been already posted elsewhere.

Hi Roman & others interested in this thread,
A 500FG is big enough on flow capacity at 42 english gallons/h (230L/h),
has a water trap capacity of 110mls and a dirt capacity at 7psi pressure
drop of 70gm's
A 900FG is big enough on flow capacity at 75 english gallons/h
(340L/h),has a water trap capacity of 305mls and a dirt capacity at 7psi
pressure drop of 300gm's so it can hold 3 times as much water and 4
times as much dirt.
A 1000FG is big enough on flow capacity at 150 english gallons/h
(680L/h),has a water trap capacity of 305mls and a dirt capacity at 7psi
pressure drop of 700gm's.
You can buy much smaller racors with similar flow capacities but the
elements if spin on will be much dearer. The beauty of the turbine
series is they throw a lot of trash into the bowl before it gets to the
element. The above flow capacities may sound large but the injection
pump returns a LOT of fuel to the tank and uses very little.
As an example I took off a CAV596 (big brother to the 296 glass bowl
style seen ona lot of older tractors) off a 100KW perkins water pump
that was going through 5-8 filters per month running 24 hours per day
and replaced it with a 1000FG and it ran for over 4 month's with out a
single filter replacement the water was drained off every 2-3 weeks. The
company that owned them could not believe the difference and we were
running the 2 micron elements.
Regards,
Craig.
