I'd stick with the EAO26 for the longest filter life, best filtration, best flow. If you pay retail plus, you should look into getting a wholesale account which lowers the price a lot.
LF697J, LF787 show up cross referenced in my book. It likely depends on the application. If you are using it with the BPEA bypass filter, it could shorten the life of that more expensive filter due to more particles getting through the fleetgard filter. I wouldn't take the chance.
fleetguard lf3941
Fleetguard FS19532
LF9001
Fleetguard LF3925
Fleetguard filter number LF3339 is Motorcraft FL400S or WIX 51516
FleetGuard FF5135
Fleetguard AF26230 Vapormatic VPD7373
I cannot find a cross reference on a Purolator, Amsoil, or Fram filter for this number filter. I suggest you write down the Generac filter model # and go to your local auto parts store. They will be able to cross reference it to the filters they sell.
Fleetguard FF5147 is the same filter and costs around $5 to $7. Much cheaper than what Yanmar wants for them.
On end of stock filter from dealer showed filter as a Fleetguard AF-25550, noted can get them for about five bucks cheaper. Also a Baldwin RS3715
I couldnt find a direct link to fleet guard from a ng7172, but if it helps, the ACDelco part for that is PF2111. (i couldnt find any cross for fleet from that, either. Or from the Motorcraft part no.)
