CAV filter issue

As to issues with cartridges, I have used a number of Fleetguard FF167A without any problem, then there was the odd one.
The paint flaking on the underside is in the "clean" side of fuel, from there it goes up through the center hole then straight to the engine, if flakes aren't so big to block the filter head outlet.

I've seen a few yacht tanks with more than enough water in to fill a CAV bowl several times over.
Personally, my boat has a fairly small tank and I'm careful to keep the diesel free of water.
That's not easy on every boat.
A piece of HDPE chopping board will float in water and sink in diesel.

Strange that the printing on your filter is upside down when compared with this photo from the Fleetguard website.

I don't have one on hand, maybe they print the label upside down on the two sides (?), and the adverts show it the visual "right side" up? The side hidden in the picture is not white, there is only a tiny blank spot around the cartridge to mark the date and engine hours
Google Image "fleetguard FF167A" shows them printed both ways.
add
there are also several different graphics: big/small fonts, red rectangle or not, etc

counterfeit fleetguard oil filters?

i worked in the automotive filter business in the predecessor of Delphi for 16 years in Engineering, even in those days (50 years ago) our agents would send us counterfeit look alikeees of our filters made in the east and labelled as our products, sold in europe. it was all too common, on one notable occasion somebody bought our scrap pile and sold it on markets as our genuine products, we knew it was our scrap because there were totally empty cans with no pleats inside, they had been put together by our engineers who were setting up the machinery for production runs-needless to say we bought a scrap bailer after that..

I cannot recognize a true vs counterfeit FG filter, I buy those at the Lorient fishing port Coopérative maritime where all the filters they have, oil or fuel, have been Fleetguard for years and years, from tiny CAV size to big filters half a meter long. Having your boat in France I think you can imagine the turnover such sellers have, they sell filters in full boxes at a time. If they are counterfeited, there must be a full factory providing all sizes of all oil/fuel filters for years in huge numbers, yeah maybe. It's not Louis Vuitton stuff, who would counterfeit a filter that whatever other sellers (Mann, Donaldson, Delphi, Hifi, etc etc) are all selling at prices +- 1/0.50 euro ?
Notwithstanding the photograph, I think such distribution network is a sign of very good products, no commercial fisherman would keep on using something which has shown being unfit once or maybe twice.
Anyway, whatever one is using, one cannot be too careful

I am not saying this film on you tube is about counterfeit production but it shows how back street manufacturers can produce a rather dubious product.

I contacted Parker Racor's tech people once for advice re the 500 series for fitting to a 50hp engine. Their reply was that the 500 was rated for 60gph flow were as the engine would require around 8 gph. Though the filter would still function they advised it be fit below the fuel supply ( ie with a header tank) to provide 'head'. Finally they suggested that in preference they would advise the fitment of 120RMAM, 200RMAM or the 110A models. Which are their versions of the CAV unit, the first two being spin on filters......

I have no idea about your engine but what are the possibilities of fitting a higher flow fuel pump and a pressure release valve after the filter plumbed back to the tank along with a 500 series filter so while running the tank gets a polish at the same time and the filter gets the flow it needs to work best, most leak off systems do this to some degree but some more than others.

Don.t forget US gallons are smaller than uk gallons 3.8 litres as opposed to 4.5 litres so 60 gph is actually is 228 litres per hour, I am presuming 8 gph is uk gallons or 36 l/hr if it was me I would still fit the 500 series.
Why:
1. the 500 is a toploader with all the advantages that brings when changing elements.
2. based on Racors statement, the 500 may have more filtration capacity and probably greater water holding capacity than the others, the elements will last much longer between changes and of course its always useful to have some spare capacity when the unthinkable happens.
3. you would be running at lower flowrate than intended hence the starting restriction or pressure difference will be lower also giving you reserve capacity
4. In flowing at slower flowrate than rated, the dwell time of fuel in the filter is longer than racor intended therefore separation efficiency is greater as separation of water at the first stage relies on change in flow velocity and gravity.

The lower flow won't affect the filters performance but will affect the lower sections performance as the turbine effect in the bowl won't spin debris and water out the same, debris and water are heavier than diesel and that is how the turbine works as it spits the crud to the outside where it slows and sinks.

Mmmm no the 8gph would be in US units as it was their tech people that generated that level not me.....and I would assume that they have taken the points you raised and others beside in coming to their recommendation. What they won't have factored in is poor location and / or lack of practical ability as and when maintenance is / was required. They do point out the possible need for providing the 500 with a head etc ( in my postulated application) that most won't be able to achieve.......

The best scenario for using the 500 unit, in your application, would be to have the tank above the filter providing head pressure.
Kind regards,
This before they go on to recommend those assemblies listed above as being more in keeping for my application, even when told that I intend to fit a high level day tank too......
I take from this that 'biggest' though eminently functional if expensive etc is not always best and the 'normal' can be equally as good........in most applications.
