Okay well here is my initial plan this is how the original owner had it set up 2x1" inch returns on each side T it off into one line have a check valve on it all will be 1" I.D line. The red squares are plugs I won't be using those holes.
For the feed section
2 outlets from overflow maybe T or Y the 1" line into one bigger diameter line or maybe just have 2 feeds directly to sump...

cool little thing I did on paint lol
Anyone see any issues please comment as it is my first time setting up a wet/dry...
