Pretty sure that is the same spring(minus the bypass) that's on the ACDelco Classic non-ecore filters that have the bypass in the block. I think that's what you are talking about.
Yep, saw one posted here not too long ago but didn't remember which exact Champ made filter it was, AC Delco Classic sounds right. Instead of six holes, has Champ type dome bypass in the endcap.
And Zee, just eyeballing it I didn't completely understand how it could work, but I'm sure your explanation is correct. Unique for sure.
