I've seen some interesting and inventive projects regarding propane "lockers", some in the archives here (when they will open!), and I'm shoping for ideas. Converting from CNG to propane on a '94 35.5 Legend and would like to keep gas out of the boat. Seen some set ups made from 8" pvc pipe and I've found some prefab lockers. Also looking on advice on "sniffers" (brand, location) and how to tie the electrics together for solenoid and sniffer operation. Thanks in advance.
