Propane Line Question November 12, 2012, 07:20:13 pm Yahoo Message Number: 135107Hello, I'm not good at looking at an object and being able to size it. How about the above floor propane lines, I'm "thinking" they are 3/8" lines. Give me your "expert" read. Also, anyone used a bulkhead fitting for taking a propane connection through the paneling? Do you have a reference where I can see a picture of the fitting? All of this is part of the project of a portable setup for our Wave 3.Thanks,Bill '08 MB Whidbey Island, WA
