CVA Diesel Filter - What ports?

[Stemar]

These CAV filters do seem to give a lot of trouble one way or another. Is there nothing better available?

I sacked mine after it blocked in F6/7 approaching Portsmouth Harbour. I wouldn't want to have to work out which O ring goes where in a rough sea on a lee shore & SWMBO screaming that the rocks are getting closer...

My friendly local car breaker flogged me a couple of filter bodies and ASAP Supplies provided taps & other bits so I've now got 2 spin-on filters in parallel. More by good luck than good judgement, I got Renault 19 or Volvo V40 (same engine, apparently) filters and the cartidges happen to be the same as the seconday filter on my V 2003, except that they have a water drain in the bottom, so I only need to carry one type of filter on board. If one blocks, it's a few seconds work to switch to the other one, primed & ready to go, and I can change & prime the duff one in a minute or two, probably, though I've never tried it, without stopping the engine. Total cost for the job was about £60. Yes, cartridges are more expensive, but still peanuts compared with other boaty bills.

Yes, without stopping the engine. I have tried it with my own changeover pair, never missed a beat.

I think if somebody could add a couple of photos it would be more informative for those thinking of converting or adding a filter.

I think that is the kind of thing I would go for if I was starting from scratch.
But having the best possible filter system doesn't mean you can neglect keeping the tank clean, or at least reasonably clean. I've dredged a few tanks with the Pela oil extractor, some have had enough water and black slime to choke several filters. I think getting rid of the water from the tank at least once a year is the most important single thing. There will always be a little bit of course, but if you keep it down to the inevitable few drops, it's hardly likely to generate enough slime to choke the filter.

Having now changed the filter, I now have to try and stop the damned thing weeping diesel!

You need to know that there are 2 slightly different sizes of the big rubber seal. If you use the correct sizes in the correct places, the thing won't leak.
