Fleetgard fl3339 same as Onan 122-0800?

Recommended Posts

I have the 122-0800 in my 90' 520h and no issues. I have the FL3339 on my 91' 520 and it seemed to be knocking a bit after oil change and is now pulled being I want to check rod clearances. 

 

Could this be the issue? 

 

Thanks

Just found this list of cross referenced oil filters for Onan 122-0800 oil filter. Fleetguard FL3339 is not even on the list!?

No idea about your knocking problem, but I believe you mean LF3339, which does cross-reference to the Onan 1220800:

Edit:  I don't know why there are so many different part numbers for each brand on these lists, or why the LF3339 doesn't show up on the Onan 122-0800 list.

"Cummins who owns Onan also owns Fleetguard"  so I ordered 2 new Onan  0122-800 filters and received 2 Fleetguard LF3339 in the Onan Green Label parts box earlier this summer, then I got with vendor and was told what I wrote in the first line, so you should be fine with the filters as far your knock IDK, Jeff.

Thanks fellas. I did end up calling the local Cummins/ Bridgeway Onan facility and they confirmed what you said. Thank you.
