The Fram website crosses the generac 070185B to a Fram PH4967 but mentions this should be verified.
NAPA Filter part #1056 will cross reference to Fram PH8172. In my case I'm applying it to a Kohler engine in a Lincoln Electric Welder/Generator Ranger 250.
Yes, you can cross reference the filters. Most auto-parts stores will have the cross reference guide. You can also find a cross reference guide on the auto-parts stores website.
You do not have to use a Generac filter which is made by some other company in the first place. Any auto parts store can cross reference the Generac filter to another brand. Purolator is an excellent filter which is sold by Advance Auto Parts.
