The fill adapter for the tanks can be made from off the shelf components. The fill hose can be obtained from Holley which is one of the listed suppliers in the data pack. There are two types, and the only difference is the color on the fitting, blue or red. The red is supposed to signify fuel lines when attached to a carburetor but it is half the price of the blue colored one. It has a 1/8 NPT on one end and a 4AN on the other for attachment to the supply tank. A longer one is available if you decide to go that route.
I bought two of them, particularly when dealing with critical ground support, one is none and two is one. They are small and inexpensive enough to keep two of them in your range box. The ASA adapter I got from Amazon as there are plenty of choices, you will need to just make sure they have a 1/8 NPT connector.
The ASA adapter does not need to be rethreaded to 13/16 x 14 the G1/2 x 14 will connect to the pin valve just fine. I attached it to the top of the tank to hold it in place and then attached the fill line.
A 7/16 wrench is required to tighten the fitting. Teflon tape helps, do not forget to do a leak check to prevent any issues during filling. The other end will attach to your supply tank of your choice.
