Airfoilmod
The mod may have the advantage of collecting the tube openings closer to the Oil, (the Heat source), but the volume of Ice has nowhere to go but collect at the respective openings into the cannister.
I would guess that the intention is to provide a smooth rapid flow into the tubes to hasten the icy slurry through. The pockets around the protruding tube ends will be stagnant areas and encourage the stuff to stick.

Where T800 is different, is FMU spill return. It does not recirculate back around the FCOC whereas the GE, P&W and all RR architectures (except T800) recirc spill back through FCOC.
I have been revisiting the fuel system diagram posted by Jet II at post 467, and it shows the LP fuel filter
after the FCOC, which also seems to me to be an unusual arrangement.
Anyone out there know why the T800 is like that??
