Are you going to keep it attacked to the hose? If so Don't bother, the CPS won't increase the power.
If not, yeah it will work. But you need a suport for the PC otherwise it will sag. I sugjest like, 4" PVC.
Get your PC at
mcmaster. It's where Doom gets his. You Don't want the wall too thick otherwise the hose won't be able to fill it.
You can't just attach a PC. You will need a barb a hose clamp or two. That will connect to a threade female adapter which can be glued to the rest of the homemade. The size of the barb and such can be determined by the size of your PC tubing. You can even make the barb a size bigger so the latex can strech over it and mabye make a better, more reliable connection.
