Fuel Filters for Volvo Penta MD6A

Scratching my head on this one... Recently acquired a Grampian with a Volvo Penta MD6A. The secondary fuel filter is, as usual, a spin-on type mounted to the engine. The primary is (apparently) the original CAV 296 filter/water separator with solid metal bowl. Unfortunately, it's the old canister type (ugh), so I plan to replace it with a Racor unit.

When I went to look up micron ratings to order replacement filters, I couldn't find anything in the original Volvo Engine Workbook. Checked what the PO had been using, and also found some postings by users, all with the same recommendation...10 micron primary and 10 micron secondary.

Huh? Isn't the secondary always supposed to be finer?? Seems like 10 microns is pretty coarse for a secondary. Anyone familiar with the old Volvo engines who might shed some light on this???

Re: Fuel Filters for Volvo Penta MD6A

I have the same boat and engine.

Nice to have someone to share problems etc with.

I am doing my oil changes etc right now myself.

Did you decide on a fuel filter? I am not sure when mine was last replaced. It is a grey cartridge with no markings on it.

Hope all is well with your boat, and if you want to discuss anything else feel free to contact me.

There is a modification to change the old cartridge type CAV to a spin on canister.
You can buy the new filter head and cartridge (not expensive) from ASAP look in their online catalogue. They may have an agent near you but if not they will happily post to you anywhere in the world
