Hi all, I am the original poster. I thought it would be appreciated if I provided an update on my oil filter issue.
People on this site never disappoint. I think that I now have all the info I need thanks to all of you that provided the great feedback.
To answer questions:
Model and Serial: Onan Marquis 7000 7NHMFA26106D, serial H933071141.
Who installed the last filter? I did. The filter that was so hard to remove was a Fram XG3614 installed hand-tight.
Thanks everyone!!
The fram chart says you need their PH10027 filter for an Onan generator. They indicate that the XG3614 fits mostly if not exclusively foreign made cars. That probably accounts for the thread difficulties tou have. Also Wix, Baldwin, NAPA and many others offer a filter line in both oil and air for Onan Generators.
