Filled tank with 110 psi everything was fine, next morning it was empty. This has happened the two times I have filled it. I hear no air leaks and the air comes out when I direct it to.

I tried to find a photo of a Kobalt 7 gallon air compressor, so the one I've uploaded is, I hope, close to yours.

Anyway, the first thing you need to check I think is whether your tank check valve is leaking.

See the tank check valve page on this site for details if you aren't sure.

Add a comment here is you have any more questions.

Cheers,

Bill
