Very quick, but this is basically what you want to do. Green is all the stuff you don't need, you can always glue it onto the shell after for looks or what not. The blue is the vinyl tubing (your air tank). The tube should come from where the air is exiting the pump and if the original was piping not tube then just cut at the redline (or just somewhere close to the valve) and stick the other end of the tube in there and goop it up. If it was tubing, just rip the tubing from the valve and glue your new tubing there. Hope this helps enough.
