Looking for pics of an ABYC compliant Propane vent on tri cabin

This is not a request for a discussion about ABYC, I am refitting the propane system on a tri cabin trawler and would like ideas on installation. My goal is to pass a survey and follow AYBC standards.

The original set up was in the fly bridge console. Just a tank, regulator and copper line to the galley on the port side. I want to put a Trident propane locker containing all equipment needed except for the line to the stove in the flybridge console close as possible to the opening and replace the copper with a flexible line. I would install a remote shutoff system also. This should take care of all the ABYC standards except for the vent.

Has anyone actually plumbed a vent hose below the sheer line from the flybridge? if so please post pics. Alternate ideas are welcome. I have no desire to argue regulatory issues, I just need to get my stove working for the admiral and get insurance, Thanks

I am not sure if ABYC standards require it, but most surveyors will write up a propane system than doesn't have a gauge at the tank. See this Trident assembly: Trident Marine LPG Propane Gas Regulator

The gauge is to test the pressure leak down of the system with the tank valve shut off.

Then downstream of the regulator, install this solenoid: Trident Marine LPG Propane Gas Low Pressure Brass Solenoid Valve Kit

Then run continuous hose from the solenoid to your stove. You can get the hose made up at a local LPG supplier for 1/3 of marine costs.
