Hi, It has been an adventure getting my new-to-me 1996 Carver 455 mechanically sound, but it seems the major stuff has been ironed out. Now it's time for winterizing and preventative maintenance. My 8kW Kohler generator has a Yanmar motor, but the serial number label is mostly covered with paint and I can't read it. The generator is so far running great, but the prior owner used various different replacement filters and I would like to know the OEM partnumbers so I can make sure I'm using the right stuff. I looked at cross-references for the current NAPA filters and they match multiple different Fleetguard filters... On the label I can make out the last few numbers above "YANMAR" ---------51340 And below "YANMAR" it appears to be TS22 5B 8 I'm sure the 8 is for 8kW, and there may or may not be something between the TS22 and the 5B. Google searches on the partial numbers didn't help. I tried cleaning the paint off with acetone and it didn't come off (at least not readily). I tried scraping but seemed like it would damage the label. I tried rubbing a pencil over paper but the paint is too thick to show. I hope you are all well in the midst of Covid-19, be smart and stay safe! Scott Naut Ohm
