1997 Onan Marquis 5000, Generic oil filter

I'll check those out, thank you

Napa part # 1348 or Wix 51348 should work

Just some interesting reading.

Best Oil Filters

FL400S
Perfect fit , and sticks out enough to get a grip on
Used a wrench from my 'cap' style set of filter wrenches to remove the old one only way to get it off

Now to find a replacement fuel/gas filter

Little screw in metal jobby

STB thank you

I have the 5BGM model generator. It had the 122-0800 oil filter installed in it. That is the substitution list that I shared in the earlier post.

yes it looks like that, the last letter in the Model number is different
that might indicate year ?
but otherwise yes thats it
thank you

I believe you generator will use the same oil filter as my 7K NHM.
I use a Motocraft FL400S from Walmart. The FL400S filters are a little longer. Makes removing easier.

Does your generator look like this?

If so the FL400S will fit.
