Im actually having trouble finding the right vacuum filter set up as well.
All the ones I keep finding advertised on Amazon or even on the autofil website mostly have pes filters dick don't work for gear filtration.
From the chart I saw about chemical compatibility the only filters that are compatible/ rated for both ba and BB is nylon or pvdf.
If u make any headway on this I'd love to know what worked for u and where u were able to find it.
Good luck
