I cannot comment on "Foam Gun" only Foam Brush and Low Pressure applications. Suffice it to say you can't put 10 pounds in a 5 pound sack and a single flo jet easily handles 4 foam Brushes and many more low PH functions thru an .05 nozzle.
I had a customer doubt that a single Flojet would handle foam brush flow in his 8 bay wash. It did, but the pump ran like there was no liquid supply to it.

Tom Hoffman used to have a video on Youtube from his Wynantskill location but I just searched for it and didn't see anything. I'll get a video at my wash when I have someone with me to hold the camera.
