anyone use the napa hose trick for the air tubes?

[AWILLIAMS64]

i was thinking about using this as an alternative to buying the air tubes for the cb77. has anyone done this? i got 1 hose already but dont really know where to cut it to make it right. The ones i have are in such bad shape its kinda hard to tell. i know i am being cheap, if i can get it to work its only going to cost me $18!
