> If there is a way to install the wall paper without removing them that would be helpful to know.

You can measure the locations of the fixtures and cut holes in the wallpaper that will allow for the opening of the fixtures. Once that is done, take a knife and cut lines in the wallpaper from each hole to the other two hole. This will make three flaps that you bend away to create an opening that will allow the hoses and the fixtures to pass through as you maneuver the wallpaper onto the wall. After the wallpaper is on the wall, the flaps can be bent back so that the lines that you cut form an invisible seam.
