Might also have a check valve to make sure the gas only goes one way.

It would appear impossible to have a flashback arrestor on the tank line due to 4500psi.

I havent been able to source cng service nozzles, i found fill ones but not the service handles like at the station, so i will be using a diy connector system that is rated for 4500psi, probably ball valves instead.

What u think of the plan?
dude it's going to take a LONG time to fill using a home gas pipe it's better to just use the station they use High pressure gas lines

the house pipe is 10psi that is at the tap

after the meter & regulator it's down to 1psi 7-10 hours fill time... if you had 10 psi at the stove the flame would be 10x bigger

source: talked to the gas man before
