Is there a filter behind the plate that the primary fuel filter house bolts to? If so how often should it be changed?

A metal screen. Remove it from the cannister and clean it every time you pm your truck. It doesn't need replacing as long as the screen isn't damaged should basically last forever. There is a small rubber gasket where the cannister seats. Make sure you hold the cannister firmly in place as you are loosening/tightening it or you risk cutting that seal. If you get a pm done anywhere they normally install a new one of those rubber seals. I haven't replaced mine in years. Suppose at some point I should just because it might crack and cause it to suck air.

dont need to clean it everytime you pm. maybe once a year. or just gut it (pull the brillo pad lookin stuff out.) and cap the end and install a valve cover breather.

Mine doesn't have brillo pad stuff in it. He may have have a different setup on primary than me. I thought it was just routine to clean it every pm I never knew they could go so long. Not a big deal to clean takes about 5 minutes.

I guess I need to post up a pic of my primary fuel filter. It doesn't sound anything like what you are describing. It's just a metal cannister shaped like an ordinary fuel filter. There is a cylindrical screen that's dropped down inside of it. There is a 15/16's bolt head on the top side of it for removal/installation. I don't know what/where any of this brillo stiff is on my rig???

I totally misunderstood what OP was asking in the first place. My primary fuel filter is mounted on the truck frame.
-
I'd like to see a pic of what you guys are talking about I have no idea. I should have not even commented in the thread.

actually we both kinda misunderstood! I am thinking about the secondary filter that mounts on the engine with the primerpump. the older e-models have a breather behind there. I thought that is what he was asking about.
