Charcoal Can Fans, should I?

I believe all the charcoal can cars 72 and later had the vent line running up the right frame rail. Short section of rubber hose into the canister.

I always liked the folks that turned them into "cool cans" - fill with ice when you go to the track to keep the gas cooler. A coil of 3/8 line inside a hollowed out one, a little fab work and it's nearly invisible.
