I want to build a marble gun using a plastic pvc pipes. usually used on faucet or home water systems. and im going to use my old air gun oxygen tank as my air tank of my marble gun. so my question is do i need to use any of this things to help me building my marble gun?

No, you don't need any flow meters. Sounds like you already have a pressure gauge and regulator. You will need fittings and a main valve. Then do the research on how to put it together and make it work.

yes i do have pressure gauge and 2burr mounted air compressor. would any of this item would help?

If you have the imagination, time, tools and parts you should be good to go.

I usually start with the barrel, normally when I find a nice piece of pipe, ammo comes in all sizes, then it's probably what type of main valve to use and how do I trigger it? Single shot, semi-auto or full auto and how to load it/charge it will be the basis of the design.

thhanks for that sir. i already done building my marble gun. but instead i use laquer thinner as my combustion to my chamber. man it really gives boom instead of pssst. but this really could kill a man instead of fun.

So don't point it at no living breathing beings human, animals or alien and play time will remain fun!

Hahaha, glad to hear it's working well!
Be very careful with it though, marble guns are known to be lethal; in 2014 a kid killed his friend with one in Vietnam by accident when the marble veered off to the side after being fired.
