Where has my Perkins/Lucas CAV Filter gone ?

[eebygum]

Unlike my last boat which had a Glass Diesel/Water Canister filter which I installed and knew intimately.... My Beneteau 35s7 has a Perkins branded filter inline to the Volvo Penta 2003 Marine and when I took it apart I was surprised that there was (A) no Filter inside and (b) The CAV Filter I had purchased fitted onto the base unit correctly but then the bolt through the unit was too short even after replacing that funny yellow plastic thing ! In the end I just put it all back together as was but surely this design is meant to take a filter ? It does have the screw at the bottom of the unit to drain off any water.

Can anybody point me in the right direction as to (A) Is this some weird 'Frenchie' design which does no take Le Filter (B) If it does take a filter, anybody know the correct size - should it be a standard CAV fit and if it does takes filter is there any special trick to put back together (i.e. is the 'Perkins' top half and the plastic funnel piece just a blank

Thanks in advance for any help

Cheers
Andrew

It is an aglomerator not a filter based on same modules
You can configure almost any way you want just use the the correct length of bolt to hold it together.

Throw away the middle bit and put a filter in.

According to the manual it is the 'Sedimenter' not the 'Agglomerator'. It removes larger drops of water before the finer drops are coalesced in the 'Agglomerator'.

Many thanks to theoldsalt for the quick response and the excellent reference pages. It's definately the Filtrap SS Version so no filter element is required. So my clean and reassembly had done the job.

Brilliant, fantastic forum answer.
