    Nearing the end of a tough install of a CJ5 poly tank under my cruiser (maybe it's that "J**p thing" they talk about). Opposite of the filler neck are two barbed fittings for 1/4" hose. I plugged one, and the other I intend to use for a tank vent. From the fitting I was going to run a hose through a gas filter to keep things clean.
    QUESTIONS: ???
    1.) How open should the end of the hose be to properly vent WITHOUT allowing my fuel to evaporate uncontrollably?
    My 66 tank had a pin hole in the filler neck.

    2.) Where would the BEST place be (other than a vapor canister) to terminate this hose end?
    Thanks!
