I posted this on another thread about the filter pump. This is the whole reason for going to a secondary filtration

Oh well either way a new filter is in and a secondary one is being installed on the cross over line. Not a huge deal for me, just something to check at 30k miles as changing it is not super simple in the middle of a long ride but something you could do if needed to. Would just need to run without it. Just a periodic maintenance issue is all.
