From my experience putting a loop higher than the PT fuel pump is not a good idea. I understand you aren’t going higher than the inlet to the PT pump. It can work but often leads to trouble with air being trapped. I would change the FF105 to a FS1000 which is a 10 micron separator/filter. It never hurts to filter the fuel to fine levels which protects the close tolerances used. When the 903 was manufactured, 10 micron filtration was not available. The PT pump has a gear pump on the rear and has a fairly high lift value, I don’t recall the number but it’s about 8” vacumn. You should be fine with your plan.
