...the vent hose bending around the top of the regulator. It does not vent the locker, but I guess is some type of safety vent for the regulator. ... help us out as to exactly what it does.
... I used a stainless thru hull vent and installed it in the cockpit. Since CNG is lighter than air, it will not pool on the floor of the cockpit.
Bill,
That's exactly the idea. The vent is there in case the regulator "lets go." So instead of "dumping" into the compartment where the tank is located, the vent line moves the CNG outside. What you've done is appropriate.
