Onan Marquis 5.5 part numbers
I have been trying to find the equivalent part numbers for the oil filter on my generator as a trip to the local Onan dealer is a 60mile round trip. Unfortunately Fram does not yet have a part number however Napa and Wix do and are more readily available than Onan. To be accurate it would appear that Wix is the manufacturer of the Napa filters.
So for those of us with the Onan Marquis Gensets, HGJAA, HGJAB, HGJAC, here are some useful part numbers including the oil filter numbers.
Onan oil filter # 122-0836
Napa # 7398
Wix # 57398
Air Cleaner element Onan #140-3116
Spark Plug Onan #167-1638
