2x viair 360c, 2x 2.5gal tanks, easystreet manifolds and ecu, UAS eurosport bags on KYB. I'm running 1/2" line from tank to manifold and then 1/4" lines from manifolds to bags. No slow leaks, but I hardly notice since my set up is always on auto pressure. The system also has leak detection and no warning have shown up.
