Did some more research to see how Merc packages their remote oil filter kits and the ones I could find, do not appear to add a different bypass valve, or adapter for the V8s
Then looked at how Crusader does theirs, the ones with no oil cooler are like Merc's no different bypass valve, however the ones with both the remote filter and an oil cooler, do exchange the original for a 20 psi unit. Which makes sense because you'd expect the cooler to add extra resistance to flow.
