Napa gold filters are good, danged good. You can also go to Fleetguards website www.fleetguard.com
and they have a cross reference search engine. I recommend fleetguard filters very highly, been working on gensets a long time. If you need, I can cross it at work on monday with a fleetguard catalog.
Fram has had their problems on industrial diesels (use 'em myself on one car, ain't bad mouthin' just da facts) so you may wanna steer clear of them. They have supposedly fixed the problem, but....... not me, bro.
