The correct Champion and the Volvo preferred for its better anti-drainback performance. The sealing ring of the Volvo looks to be a little smaller, but they measured at 2.79" dia (Volvo) and 2.81" (Champion) so insignificant.
Cellophane covering for the (boxed) Champion, don't recall this before 2010
Just for interest, the by-pass valve (allows oil to flow unfiltered if the filtration media becomes choked) of the Champion, internal depth to the end of the valve is 2.785" and to the end of the canister 3.495".
The Volvo bypass valve, 1.77" to the end of the spring and 2.57" down the centre of the spring, which is approximately .585" internal diameter. My tube is 2" high, so plenty of clearance even with the shorter My tube is 2" igh, so plenrty of clearance even with the shorter Volvo filter.
Three frames from the YouTube video measuring the depth of filter 1, which gave zero oil pressure ...
... comparing the depth of filter 1 to the anti drain-back tube - little if any clearance ...
... and Comparing the depth of filter 2 to the anti drain-back tube - maybe a couple of inches of clearance
Of course the same thing could have been done by putting each filter beside the anti drain-back tube, probably to greater effect and in a much shorter video, but some people just love making things more complicated than they need to be, and it would have been much more helpful to tell us how high the bad filter was!
