M932a2. Air dryer blowing air

your system still has 100 psi pressure after 8 hours in both tanks?

You could turn it up a little if you want or leave it. 125 really is fine.

Juanprado. Yes it was still holding 100 psi after about 8 hours

Wow, Mine definitely does not hold that high for anywhere close to that time. I have maybe 60 psi after just a few hours or so.

Do other's hold air that long on here?

Thanks,

I hold air in one tank longer than the other. I definetly have 60 or so psi after a few hours. I'm sure if I went over every air fitting in the entire truck I could hold air a little longer but I am pretty satisfied with how it is. When I got the truck it had small leaks here and there it took a few days to correct all of them.

Same here, maybe 60 psi after a couple hours..I've had several 939's and none of them have ever held for extended periods. I don't really care though, it does not take long for the truck to air up.
