Surgical tubing (rubber). You can use a .177 pellet from your favorite pellet gun to plug the end........and 2 oz. syringe to fill it up! Real simple. You just need to install a smooth tube inside your wing to house the expanded tube. Fuel proof it real good in there, so when it explodes on you....it won't soak the inside of your wing!!

Enjoy

You can purchase the tubing at any surgical supply store...........
