Good catch on the pump!! The top barb is OUT and the side barb is IN.

Besides ensuring that the res OUT goes to the pump IN, in this small of a loop it won't make a bit of difference whatever order the sequence is, IMHO. Other than the res/pimp relationship, order everything else in the simplest path without kinks or excessive tubing.

Of course you can try it different ways to see if there's a difference.
