Anybody concerned about buying fuel filters that are not Merc, Crusader, Westerbeke, etc? I just got a service bulletin on my WB genny telling me to switch to a new part number for the filter. Seems last year's filter with its paper element is dissolved by e10. I wonder if Nappa, AutoZone and other places are selling the e10 proof (metal element) marine filters. Seems as though they should, yet I ended up with a paper element filter last fall that must be changed now, and that was a WB part.
