At my old house that was a stem wall construction, I waned to run a gas line out to my gas grill in the back yard. The only source of natural gas was under the house in the kitchen. The real issue was the kitchen was as far away from the under house entrance as possible. So I got to crawl on my belly until I discovered the air conditioning supply line was blocking my path. So craw out, get a shovel, and shovel a deeper path under the vent, while on my stomach. That took a while, and I finally got back there, and made my connection, and I never had to worry about running out of propane ever again.

Only because I was in my 30s could I have done that project. Somewhere I have a photo of that gas grill burning off the old food grease with 8 inches of snow on the ground and a path I shoveled to get to the grill. I cooked a lot of meals on that grill.

You will want a very solid non flex connection is it is under constant pressure like that. You sure don't want to come home and find water running out from under your house and have to shut the water off to the entire house as the swamp under the house drains down. You might want to add in a shut off ball valve to it as well.

Good luck. Working under a house is not fun. We have a slab foundation house now.
