Ignore that ATJ recommendation and install the filters between the pump and the turbines if you choose to install them at all. ATJ is trying to save trash from getting into the pump, but as discussed most of us filter the heck out of the fuel before it goes in and then the UAT serves as a great filter ahead of the pump as well. Could make for an easier install also. That’s if you choose to run a filter. I do, along with everyone I fly with, but I unsderstand lots of people have had both success and failure with either method so to each their own.
