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
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???
