[C320-list] racor primary fuel filter

[David Swanson]

I just changed my fuel filters and bled my fuel system of air yesterday.  

Im not sure what the plastic screw is, I was wondering the same thing...  The bolt is the bleed vent.  

I replaced my filter with the Racor R20U filter.  This is also a 10 micron filter.  My boat came with a 10 micron filter as well.  

The mechanic at the local Yanmar distributor said that given the small fuel usages rates of these small sailboat engines, you could use a primary filter down to the 2 micron size, although it would be overkill since the engine mounted secondary fuel filter is 2 microns.

Anyway, I just changed mine, bled the air from the system using the Racor filter housing hand operated fueld priming pump, and all is well now.
