I followed the plan for the refill adaptor and although it took some time to order all the parts, when they came there was no machining to do. They cost $130 including shipping. They all went together with nothing more than a wrench and vise. I drove to the public refueling station at Newark airport; the connector worked fine; the fill-up took about 20 seconds; the only surprise was the pump agent who was wide-eyed that all he could charge me was $1.15 to fill the tank.
Previously, I was paying $140 for shipping a tank to Corp Bros, having it filled, and shipping it back. The cost of the new adaptor was thus amortized in a single use! The New Jersey gov is intent on encouraging the use of more CNG, and the cost of CNG is going down, so I am hopeful there will be more refueling stations emerging. That should create more of a market amongst boaters, and bring more CNG to the shore.
