[C320-list] Fuel Filter

[jim brown]

Maybe I'm missing something but if the primary filter is a 2 micron then there should be no particles or sediment that wouldn't go right through a 10 micron secondary. Only advantage I see is that you probably will never have to change the secondary. 

My Yanmar came with a 30 micron primary which is still recommended as the proper size at the Mack Boring diesel courses for the 3GM. Something about two low micron filters putting stress on the fuel pump if I remember correctly.

I have a Perkins M30 and a Raycor primary fuel filter. The secondary filter mounted on the engine is 10 micron. The primary filter is a Raycor R20S which is 2 micron. This was the set up when I purchased the boat a year ago and Ive always thought the primary should be at least 1o, perhaps 20 micron. Just had to replace the primary after only about 50 hrs of run time. Can anyone weigh in on the correct set up for the M30 ??
