Hi people. What are the go for ease of fuel filter upgrades I have researched a little on the kdj120 found the stock filter is approx 16 micron. Sussed out a fleet guard upgrade to the cav glass bowl type ff167a and they offer 12 micron . Do we all believe this is good enough or can we do better without compromising Inlet fuel restriction reaching performance hampering levels. Thanks in advance.

My Thread Why it is necessary to quote Beta Standards when stating microns

Suggest you read my Thread: as it answers your question.
It is vital that the fuel filter supplier quotes the % efficiency as stating the micron alone is totally meaningless. It is absolutely essential that you know and understand efficiency ratings. Donaldson Filters have a easy to understand explanation on their website in the Toolbox section. http://www.donaldsontoolbox.com.au/t...e-air-filters/
Mann Hummel is another. Both these companies produce prefilters specifically designed for modern common rail diesels such as Prado D4D. Mann Mummel's filter comes standard with an electric warning buzzer. Both have water traps similar to the std Toyota filter. Beware there is a fallacy in the statement by a supplier of a water trap that fuel filters with water traps do not work in removing water. Both suppliers quote the % efficiency of water removal of their filters on their websites.
Premium filter companies will quote % efficiency, flow rates. and capacity. All vital figures that must match your engine. A 4 micron at 99% efficiency filter for example can have a flow rate too low for your engine causing restriction. It could have a small capacity so that it needs replacement in say say 1000 km.
Why do some people only quote microns only when it is meaningless gobble de gook.
If a supplier does not quote efficiency or the other criteria referred to above move on to a supplier who does.
"Buyer be ware"
I have no affiliation what so ever with ant filter company. No doubt there are other premium filter companies beside these.

Yes PW 114 LPH is the correctflow rate for the Prado D4D motor which in addition to fuel usage recycles the fuel.
The OEM filter or its equivalent specification is designed to give correct fuel flow sensor readings so it needs to be in a position to do that.
It has been found that a high pressure common rail diesel requires a 3 to 2 micron at 95 to 99% efficiency filter and I refer you to Ryco Parker Hanniford website for an independent test. Parker is another high end filter company. Ryco sold out to Parker who have been upgrading the Ryco range to cater for the demands of common rail diesels.
Filter companies such as Mann Hummel, Parker and Donaldson have entered the 4x4 market by developing filters that are specifically designed for the modern common rail diesels and their needs. They manufacture specific OME replacements for the Toyots filters and offer prefilters. Their OEM filters are very slightly higher in specifications than the original eg Donaldson replacement fuel filter is 10 micron at 99% versis OEM 11 micron. I use Donaldson filters simply because Maxiparrts a stockist is nearby and their prices are the best. That is my only connection with them or any other manufacturer.
In summary fit a prefilter of 2 to 3 micron at 99% then the OEM filter then the fuel flow sensors. The reasons for this setup are there on the websites of the filter manufacturers I mentioned. Grab yourself a big cup of coffee get on their websites and read everything you need to install your prefilter setup. They all provide personal phone support so take advantage of it if you still have queries.

Thanks Kitbags. I had settled on the Donaldson Prefilter, as their website was the only one I could find that actually gave microns (2) at % flow at the LPH flow rate, plus water separation figures. I will probably move to their OEM replacement when out of warranty. One more question, just wondering why you mentioned the "Fuel flow sensor", where you did.
Cheers, Phil

The Toyota filter already fitted to your Prado as standard is 11micron at 99% efficiency. This filter is both a lower micron rating and a higher efficiency than the filters you have fitted.2007 120 GX, automatic, diesel, 2in lift Bilsteins King springs, rear swaybar extended link pins, ARB lockers, TJM bull bar and bash plate, dual AGM batteries, Provent 200, Donaldson prefilter, Uniden UHF radio, IPF driving lights, Koita fog lights, roofrack

The results of this testing are used by the large international filter manufacturers such as mentioned in my previous threads and posts.

I suggest you take the time to read the independent test experiment that determines the wear in high pressure common rail diesels caused by different particle sizes in fuel.

There is literally NO reduction in flow of fuel, even using the 5 micron in the secondary position.Stan Miko

i got advice from allan grey here in Melbourne at terrain tamer. hence going with a 30 micron water separator filter set up. im no wiz at this stuff but the advice given to me by the tech wiz in store is worth gold. Berrima Diesel say the same thing and have back up of their words in their videos.
