Near-north Ontario, French River | My bad towman, you are correct that the dryer should come before the tanks. Unlikely but how about air ride suspension with a blown bag. Air isn't generally sent to suspension(and other accessories ) unless system pressure is greater than 60ish psi. If secondary tank isn't going above 55ish I'd be looking to suspension or other accessories ( cab suspension, pto controls, pointless hook if equipped, even air power wipers etc). If the leak can't be easily heard it must be a large leak ,ie blown bag or severed/disconnected line. |
