do u have check valves installed if u dont u will also leak, when i had air cylinders on my acura they leaked and it wasnt the cylinder it was the valve, if u dont have alot of pressure in your tank, your cylinders loose pressure so u have to use check valves, also make sure u use the brass filters on the bottom, this stops dirt from getting in, and even the cylinders are rebuildable they are a pain in the ass to take apart and put back together, i just went with new cylinders.
