I've seen something that attaches between the water bottle and the frame, and has something that comes out to the side for mounting a pump.
At one point, my road morph was mounted on the bottom side of the down tube. I put plastic wrap so that it wouldn't get too dirty.
may I suggest this version(easier to read gauge which isn't any more in the way)
Yes, my road morph gauge is hard to see. If they would just color code the different pressures, it would be fine.
