The Volvo (reputedly a Mann 917/1) preferred for its better anti-drainback performance, and the correct Champion. External height of the Volvo 3.25", the Champion is 4". 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 hopefully insignificant. A subsequently purchased Mann 916/1 measures about 3.75" (95mm) external height i.e. close to the Champion.
Cellophane covering for the (boxed) Champion, don't recall this before 2010. The Volvo filters aren't boxed but come with a flimsy plastic end cover pushed into the threaded hole.
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 and the tube were!
Some filters have a single-piece pressed end-plate with just a moulding to centralise the filtration cartridge, like these stills from a video of a Fram PH2800 series - GFE121F remember - that showed the collapsed filtration cartridge, i.e. it had no (effective) bypass valve. This is just a simple pressed steel spring to block off one end of the filtration cartridge and to press the other onto the end-plate so all oil has to flow through the filter. This is not a bypass valve, and maybe coincidentally the video shows how the filter cartridge has collapsed, quite possibly from excessive pressure. Some filters with this type of end spring do apparently have a bypass valve as part of the anti-drain valve i.e. near the open end, but they are much harder to identify unless you cut the filter open.
This Fram PH8 does have a plastic bypass valve in the end spring ...
... but it also has a damn great hole in the filtration cartridge where the ends of the filter strips haven't been crimped together correctly!
The by-pass valve of the Champion (Halfords price £4.99, or £4.19 for their own make), is 2.785" to the centre of the valve, 3.495" to the side of the valve. Because this shows a 'rectangular' plate spot-welded to the end-plate inside the core of the filtration cartridge, and given the differences in depth between the two parts, you can be fairly sure that there is a bypass valve between them even though it isn't visible as such.
The Volvo bypass valve, no doubt about whether one is there or not as the spring is clearly visible. 1.77" to the end of the spring and 2.57" down the centre of the spring, which is approximately .585" internal diameter, i.e. more than wide enough for the tube to fit inside. My tube is 2" high, so plenty of clearance at the end even with the shorter Volvo filter.
The innards of the Mann W916/1. Has the spring like the Volvo but oddly only has two rows of perforations at the closed end of the former for the filtration cartridge, whereas the Volvo and all the images and films I have seen of other filters have the perforations the full length (however a second look at the photo of the Champion filter above also seems to show only two rows, I'll have to have a closer look when I take it off). External length of this filter is 3.75", internal depth to the end of the spring 2.13", to the centre of the bypass valve is 2.99", internal depth to the side of the bypass valve is 3.31", max diameter of the sealing ring is 2.78", and width of the sealing ring is 0.16".
The Unipart GFE 422 (retail £3 inc VAT) interestingly has a similar former to the Mann i.e. just two rows of holes at the closed end albeit with a smaller number of larger holes. It does not have the visible by-pass valve spring of the Volvo and Mann, but does have what is almost certainly it's equivalent. External length of this filter is 3.5", internal depth to the centre of the bypass valve is 3.07", internal depth to the side of the bypass valve is 3.31", which gives a much smaller overall distance for the valve (less than half an inch compared to more than an inch and a half for the Mann). Max diameter of the sealing ring is 2.83", and width of the sealing ring is 0.18".
