I moved the tubes to be almost flush with the foam matting and then "Elmer's Glue " around the tube to seal. Elmer's did not "attack the foam". Results ? Water tight seal like your kitchen sink drain. You can pull the tubes out to feel the foam and where you need to be with the tube edge height. But first, you should unbold seat. Move back and forth to "lean" seat back to gain access to computer. Dry area, unplug computer , clean and spray connections with Fluid Film spray . I disconnected the battery after seat position was clear before unplugging computer.
