Onan has been packaging Fleetguard LF3339 filters in their green boxes for several years with the 122-0800 number on the outside. If you want to save money, search for the Fleetguard, green boxes can be expensive. The one thing that I don't like about the Fleetguard is that it has no flats for an oil filter socket like the 122-0800. Be sure that you have the rubber grommet around the filter to seal off cooling air, most are discarded by inexperienced owners. 3 Share this post Link to post Share on other sites

Meaning I'm happy to have the Vanguard style system that stops the engine when oil pressure falls low enough. I'm responsible, but the sun is brighter than that LED. Not to mention many 520s have problems with that warning light, and I've seen several tractors that the light has been on for years and no one thought to figure out why. My Vanguards won't fire at all until oil pressure is at 15psi. And the coils are grounded when the pressure falls below that point. Not sure how to make it work with an Onan that requires a 12v source to fire. I'm guessing those same style pressure switches can be a "normally open" version that can carry the ignition wire. I mean, that’s the way it supposed to be! I cannot remember, but it was some motor that was low on oil and it shut down… maybe a Honda. Share this post Link to post Share on other sites
