Only 8 months after replacement, ACS failed again

Ray sounds like you're at least comfortable with it's current rideability. Now to determine if there's some kind of leak in the system. Top it up to 60 lbs AFTER your next ride when you know you won't be riding it for two or more days. Then check the pressure after 48 - 72 hrs and see if it's dropped just the pressure gauge loss amount, or significantly more. I think the brass check valves are prone to sticking open and now know they can be cleaned (at least mine could be). I can set my pressure with my air chuck and 3 days later it's the same pressure now. Before it would drop below my gauge's lowest reading.

I intend to check this as you say, for a few times. I'll let you know.
