[C320-list] Fuel System Filters

[jim brown]

I think engine hours is only one factor that has to be taken into account when deciding when to change fuel filters. Others are geography-in the ice cold north not much grows in diesel for at least half the year, whether or not you use a bioside  the quality of the fuel you put in the tank, and the amount of time the fuel sits undisturbed at the dock. Also the frequency of changing the secondary filter does depend on the filter size of the primary filter. I believe Yanmar at least suggests using a 15 micro primary but some usesvdown to av2 micron as the primary.  If your boat sits all summer in Florida using the engine only few hours may lead to a plugged filter pretty quickly the first time you're out in a seaway when the fuel gets a good mix in the tank. Filters are pretty cheap insurance

  Since I only put about 50hr on the engine each season I change the
  filters every 3 years. I would do it more often if I detected any
  grunge/H2O in the RACOR especially; I never have.

    Every Spring I change the Engine fuel filter and every two years the
    Racor filter. I never find any contaminate or moisture evident in
    the bowls.
    The Yanmar filter looks as pink coming out as the new one being
    installed.
    Both filters were new last Spring and I put 130 hrs on the engine
    since.
    I believe Yanmar recommends 300 hrs for their engine filter.
    Any comments welcome on needing to change filters as frequently as I
    have been, etc.
