Replacement Fuel Filter - CAV Style

[znelbok Member Find all posts View Profile Close znelbok]

Has anyone changed their fuel filter over to the more standard CAV style filter.

There are adapter available that screw in to accomodate the filter itself and of course there are comlpete units for a direct replacement.

These filter are really cheap which is why they are often used and from my understanding a more industry standard style (hence they can be made cheaper because of volume).

CAV adapter


comlpete new housing etc.


I have a comlplete replacement unit in my hilux. The glass bowl allows you to see any dirt that has been trapped and dropped out. I am thinking of changing over the 1KZ filter to this style as well.

Any comments on this and/or any reason why it would not work.

Looks very similar to the water seperator a lot of us d4d guys are using in conjunction with the factory filter.

[znelbok Member Find all posts View Profile Close znelbok]

Yes, but they are not a seperator, just a filter (AFAIK).

i think this is the style most folks use, it does state separator...

there's also the Racor 230R which is a filter and water separator.

Yeah, the Fuel Manager kits would be Classified as 'industry standard' fitment. There are others for sure, but the FM are the more popular kits.

Personally, its our pick.

I personally would not use a CAV type filter as there flow rate is only around the 45 litres/hour mark.
While this may sound okay compared to fuel consumption rate per 100km, all diesels flow more than they use and common rail engines typically flow and return a higher quantity. I don't know the flow rate of the Prado engine but I do know of 2.5 litre diesels that flow over 200 litres per hour so I would expect the 1KZ-FTV to be similar. A side effect of the high pressure and flow rates is the increased fuel temp which necessitates the fitment of a fuel cooler.
Fitting a prefilter is a good idea but check it has a good flow rate to prevent possible issues.

Hi Lee,
i think its for the reason of flow that most people go for the fuel manager, quick google supplied these results:
FM10 Series - up to 200HP
• Max fuel flow (inc. return flow) 190 Litres/hour

FM100 Series - up to 350HP
• Max fuel flow (inc. return flow) 300 Litres/hour

FM1000 Series - up to 600HP
• Max fuel flow (inc. return flow) 300 Litres/hour

Finally fabricated a bracket for my new filter. Parker Racor 230R series with a R20S element. 2 micron. With primer.
Bracket uses the two bolts that hold the original filter with a third bolt on a leg mounted to the inner guard.

Placed in line after the Toyota filter. Some recommend fitting in line before the original filter but cannot understand why you would put a finer filter in front of the standard one.

The 3 bolts are easy to remove for servicing, only need to drop the fuel lines, remove all 3 bolts, unclip the sensors and remove complete from the car and service on the bench. Same to reinstall and with both units having primers easy to refill.

You mention a Racor 2 micron filter. At what beta rating is this filter 5,10, 50, 75 etc?

[Rusty62 Advanced Member Find all posts View Profile Close Rusty62]

2 micron is super fine. 30 micron is course.

Please refer to my post "Why it is necessary to quote Beta standards when stating microns" which is in the General section of the forum.
This post and attachments explains how filters all 2 micron can have efficiencies that vary from say Beta 2 (50%) to Beta 100 (99%) efficient. All are 2 micron filters. The first 2 micron filter at 50% efficiency removed only 1 in every 2 particles that are 2 micron in size. The second 2 micron filter removes 99 in every 100 particles that are 2 microns in size because of the vast differences in efficiency. Quoting microns alone tell us nothing about the efficiency of the filter. The manufacturer should state the efficiency on their website. If we know the Beta standard or percentage efficiency of the particular 2 micron Racor filter we can then match it to our requirements and compare it to other filters. Only then are we comparing apples to apples. Hope this helps.

Filters specifically designed for high injection pressure diesel engines are available. Why are these necessary?
Manufacturers of these common rail diesels have established a standard of cleanliness for diesel fuel that is to be used in these new engines.This is critical requirement for these engines to avoid component failure. It is not the composition of the diesel that is the issue but maintaining the high level of diesel cleanliness that must be achieved when used in high pressure injection systems.The fuel manufacturers supply diesel to the standard but contamination happens somewhere after that.
The specific job for an auxiliary filter is to clean the diesel fuel in your Prado's tank back to the engine manufacturers required standard of cleanliness. Mann Hummel and Donaldson websites have detailed explanations of the required clean fuel standards, the fuel contaminants and their new filters specifically designed for high pressure injection systems. Also how and where to fit them to achieve the known specific standard of clean fuel required by your engine. Both have aust offices so just phone them. Gees that reads like an ad for them. Well i don't have an interest in them.
There are probably other filter manufacturers who also have filters specifically designed to achieve the required advanced standards of fuel cleanliness demanded by these modern engines , I just know of these two from experience. The information on their websites and other unrelated sites can be used as a yardstick if you are contemplating filters from other manufacturers.
I urge you to spend time researching before fitting a second filter. Picking a filter not specifically designed for this job is risky as it could be a recipe for tears down the track.
