to keep the indent on the far right in line with the supply, could the supply manifold be built reversed, ( not flipped end over end) the air fittings to go on the other end. The manifold has more space before the threaded end on one side. this adds a bit of offset and seems to align all of the ports. The issue may be the bracket holding the supply at the correct place in relation to the mixing station output. Any problems with this??
