Anyone out there make there own hoses for the fragrance assembly? Coleman is up to $275+ for the whole thing (gun, hose, etc), but it's usually just the hose that needs replacing. They use a wire-braided hp hose, which seems like overkill since it's just a hose that holds the tubes (nothing actually flows through it). Anyone have success with any other types of hoses that can stand up to the constant bending, twisting, etc?
