Bit of a propane noob here, figuring stuff out googling best I can, but the vendors' CS reps aren't forthcoming with answers to end-users with unusual use cases.
I will be having our propane dealer (currently Tractor Supply) do all the fitting and installation, have them train us on the (yes I know critical) safety procedures etc, but I really want to know what I'm doing, have the list of fittings ready before I approach the certified techs, or they're likely to turn me down for liability red flags.
I want to purchase new 43.5# aluminum tanks designed for fueling forklifts, and repurpose for vapor service by adding a standard 1-1/4″ ACME/FPOL Type 1 QCC valve.
So far it seems Worthington and Manchester are the main vendors, but I can't seem to find out if there is a 6-hole SKU with the view gauge and stock filler valve in place, with a (plugged) hole on a tank available for that added fitting.
That should be in location C in this diagram:
If not, I believe I can remove the stock Filler Valve (location B) and replace it with my standard vapor service valve, but that means sacrificing the liquid quick-fill capability, as used by AutoGas stations and propane delivery trucks.
I did find a Rego dual-service valve 8555DL that apparently provides a 1-3/4" ACME liquid fill valve as well as vapor service, but since that is a pretty exotic fitting, would prefer to find a tank with the extra "optional" hole available to use with the standard valves.
Or maybe I can replace the view gauge with a service valve? I don't know the hole thread specs though.
Any advice greatly appreciated, including links to a more appropriate forum with more expert gas techs willing to help an amateur.
As a side note, anyone know how to get certified in this stuff - online, distance learning, or SHORT courses if onsite attendance required - without being currently employed in the industry?
Thanks in advance.
