Does anyone have a cross reference for oil filters for an Onan 20hp? Also is the thread 3/4-16 or metric? Will a
Fram PH3614 work? Or a Motorcraft FL-910S? Or a number for a longer filter.

According to this page, it's a 3/4-16, 30 micron, 8 to 11 PSI bypass relief with 3-in OD.

Somewhere on the web is a really comprehensive wix catalog of products that has some popular cross references. You could look up those specs in the wix catalog and see what filter it would cross reference to.

I don't know the specs on a fram pH 3614 so I can't say if that'll work or not.

The 3614 will work, I usually run the 3600 on my P218. The 3600 sticks out further, easier to get ahold of to change and takes an even 2qts of oil. As long as it doesn't interfere with say a loader
