perhaps, but the rate of pressure drop on tank vs bag is more on tank. 30 psi tank drop vs 10 psi bag drop.
coudl it be a valve in the vu4 manifold not fully seating?

here, thsi video might work now:

well ill be damned. the tank stopped leaking. same psi overnight. maybe was dirt trapped in valves.
Weird thing though, it has a cross bleed issue it seems. front rigth goes down a few psi, front left goes up a few psi...
Also when pumping up both front at same time, the front right (furthest from teh manifold) is always underinflated by like 10 psi compared to left bag.

what did you do to fix it? Or did it fix itself?

Greg5OH

totally fixed itself lol. I figured might be some crud stuck in the manifold somewhere. Even if it was, i dont know where the air was going to...anyway pumping up and down buch of times, was still leaking. Drive it to the gym and back, then noticed tank pressure was solid, and it held ever since...weird.

huh, thats wierd. hopefully that happens to me. lol. I got home from work today, checked all my fittings and lines with soapy water..... can't find a leak anywhere. but psi in tank drops about 15 psi over 7 hours

does it drop at night time???? you do know that air does expend doing the day

I do know that, but it would drop like almost 40 psi every day after 4 days it would be at 0psi. But like the op, it stopped leaking like 3 weeks ago. Weirdest thing. I still don't even know why it was leaking. Now it only drops like 3-5 overnight but day time is fine. So I'm not worried about it.

swtjlsy i have to say i finally understand what you mean with elevel that it will manage everything.
My systme uses the traditional pressure sensor which is connnected to the solenoids which turn the compressors on and off. Basic system, on this psi off this psi. Just realized e-level will adjsut your on off pressures automatically to make sure you have enough pressure to get to full height without the compressors turning on. SO my system is a 150psi system, and witht e volume of the lines, bags and tank, the compressors will turn on if i try raining all 4 corners at once from full dump. I tried a bunch of 175 psi switches which didn't work (i realize i had them wired differently)
but elevel will find the perfect pressure for you!.
elevel-one day...dont have 1k for it currently.
Plus I dealt with shay quite a lot regarding my vu4 last week and he was always helpful and courteous, vs dakota digital tech support...the guy was telling me the solenoids which let air in or out send a signal to the dakota ecu to tell u what pressure the system is at.,...i hung up the phone.
