1997 Onan Marquis 5000, Generic oil filter

It's been that way for years. IME, anything that says Onan on it is at least double the price as the the same product that has the OE manufacturers name on it. Onan makes generators and engines. Most of the ancillary parts are made by someone else.

P.S.: NAPA doesn't make parts either.

yeah i know, NAPA is simply a rebrand

if i get a NAPA number anyplace can cross reference it

or i can do it my slef on the web

Found this Oil Filter Cross Reference When I was looking for a replacement for my Onan oil filter.

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.

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 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.

STB thank you

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

Just some interesting reading.
