I'm having a hard time replacing the Racor fuel filters on my 18 Yanmar. Does anyone know the microns for the R-11 primary filter (at the engine) and R-110A filter (secondary)? Thanks.
Use a band wrench. The one with a rubber band and a plastic handle. It's handy to have on board. In an emergency just screw a length of webbing to the end of a stick. Turn the stick will tighten the webbing.
