Replacing old CAV filter - advice please

[Latestarter1]

I have not even looked as I have only been on the boat when the headlining needed sorting out, but I certainly assume there will be another engine filter.

I seem to have stumbled upon the only supporters of CAV filters in the uk... does anybody think I should bother changing it? Where's Latestarter when you need him?!

Been working to earn a bob or two to keep a shirt on my back.

CAV filters were great in the 1960's and that is where they belong. Diesel engines as well as fuels have progressed out of all recognition, clue is in the name, how long ago did CAV exist as a company?

Poor capacity, stone age non coalescing filter media (clue lays in the price of new element) which does not comply with filter industry Beta ratios , absolute fiddly pain to change. Clear filter bowls, hate them, go yellow and opaque over time telling you nothing.

Racor is OK but a 1970's product fiddly to change and expensive solution.

My choice for this simple installation spin on Fleetguard FF105C. Zillion times the capacity of the CAV element. Soo simple to change, spin old one off and new one on, no pesky O ring to drop in the bilge.

Called progress.

FF105C sounds like good advice.

I've got Racor R25S with bowls and FF105C appears to have same thread and approx. outer diameter. Can't seem to find any info on compatibility, would any of you gents be able to confirm if a direct replacement is possible?

Hi Latestater

Thanks for your reply, I knew your eye's would catch CAV in the title and you would respond when not so busy. So with your recommended Fleetguard filter http://www.partsandfilters.co.uk/fleetguard-ff105c-fuel-filter-p-973.html you simply unscrew what is there at the moment and screw this on the the old CAV top section and job done?

If so I will recommend that and get my liitle Racor R12T on fleebay

Cheers

The fleet guard product will still contain a filter pack of pleated media similar to the CAV and dimensionally the actual pleated pack is probably the same module size as the CAV.


The fleet guard Like the CAV element can only coalesce by virtue of the free water dropping out of the fuel when the flow through the canister changes velocity. Filter life how can you judge? no element is going to last forever but on a road vehicle the CAV's may last for thousands of hours. The OP is using the CAV in an application where the max flow is 5l/hr the CAV product is rated at 46l/hr so you should get about 9 times the predicted life at rated flow.

Fleetguard is not a direct replacement for the CAV,so you will need to buy and fit a new cast housing with a threaded spigot as opposed to the push on CAV element and when you come to change you will undoubtedly need a special tool to spin it off or bash a screw driver through it. you pay yer money and take the choice.

CAV Clear filter bowls go opaque, well they might do, but you can easily drop it off and clean it whereas the fleet guard you can't see any sediment or water because it has no visual indication you have to open the tap and drop what runs out into a can for inspection.

One final thought the CAV is minimal in terms of the amount of steel and paper you consign to the bin at the end of life, the fleetguard is a much bigger steel housing with built in drain and the threaded plate on the top is quite a chunk of steel all of which has to be consigned to the bin..........-what a waste.
