Three liter tank times three

Three days using new three liter tank and as I said in another post am very pleased. However ever ever it doesnt last to long.
I didn’t count fills on my Daystate revere because I was filling at different pressures testing hammer adjustment but this evening decided to go bigger. Was thinking the 6 something liter but looked at physical size and said go for the 9. Hopefully the Gx4i can fill. I’ve got leaking problems with the gold water filter from Amazon somewhere , the 3 liter kept getting to about 250 bar and then loosing air. Been happening since I got it last week or so. I’ll take a look at it tomorrow.
Filling to 300 bar was making me nervous so instead of the Chinese valve and gauge got Topgun air’s valve . I don’t know if it’s really better but their video sold me on it. This is for the new tuxing 9 liter.
 
The 9L is a good size - I bought the Acecare. Joe's valves are great, but double check to make sure that the threads match. My tank came with M18x1.5 threads, and I suspect the Tuxing might too.

If Joe's valve has imperial threads, Saber Tactical makes an adaptor that allows imperial valves to be used in metric threadded tanks, if you find they are different . . .
 
My new Tuxing 3 liter that came with valve is leaking since received. Took valve off , nothing noticeable.
Bought through eBay and contacted today, they said send pictures . Waiting for reply
