I purchased some flow spinner things from Mountain High so you can see the oxygen flowing each time you take a breath (sometimes its hard to detect). The whole thing weighs 4.1 lbs and is all medical grade stuff.
The regulator has 5 settings for the amount of O2 per breath or can go continuous. At the highest setting the 170L of O2 last 3.2 hours and 10.1 at the lowest. Set it based on your pulse oximeter. Mounted the whole thing with a fire extinguisher mount.
I get it filled at Roberts Oxygen. They gave me a bit of a hassle the first time, but once they stuck their label on the bottle, it wasn't a problem after that.
Could send photos if you want.

I had a couple of people ask me about my DIY system I put together for the limited space in my Long EZ. Here the description I sent out...
The O2 system consists of a small bottle, a demand style regulator, cannula, a carrying bag, regulator key, a pin wheel flow indicator and a mounting bracket. I bought an adapter so that the medical bottle could be filled at an airport, but I have never used it because a bottle lasts so long. The whole setup weighs just over 4 pounds.
The bottle I used was an M6 size bottle which holds 165 liters. With the pulse demand regulator, that can last from 3 to 10 hours depending on the regulator setting. These are medical bottles and have a special yoke style regulator for a post valve. Get whatever size you think you need. The little M6 I have is about 12” tall and 3.2” diameter. Surf around, you can get these new for $50 - 75.

The cornerstone of this setup is the Easy Pulse 5 regulator. It has 5 settings and you can dial it in for however much you need based on your pulse oximeter indications. This is a yoke type and only works with medical bottles. $100-150

I used a fire extinguisher mount from Spruce and bolted it to some hard points in the strakes so it was in easy reach. $17

Close to the bottle and in view, I had a flow indicator. With all the noise and air movement in the cockpit I had a hard time telling if I was getting O2. This gives you a visual indication.

A carrying bag you can get on Ebay or just about anywhere else for $15. A lot of times they come with a wrench to open the valve and or a cannula so watch for a combo deal.

If you are willing to go preowned, you can find most of this stuff for 50 to 75% less than the new stuff I have linked.
I also bought a boom cannula from Mountain High I think. In the cockpit of the Long EZ this was a must. I super like this cannula.

I also where the pulse oximeter around my neck. You can get those just about anywhere. I think Anti-Splat is selling them as well.
There is an adapter you can buy which will allow the medical bottle to be filled at an airport or welding shop. Its in my hangar still in the box... I never used it. A retired fire fighter friend said you might talk your way into getting the tank filled for a generous boot donation. The adapter is made by Western Gas and Control Technology model M87-1. Here is a link to the company, but I don't know where I found it, ebay I'd bet.
