Please tell me what this line does

12 years ago

Hello, I have a Speedaire 3Z495 air compressor. It had a line coming from the head cut and crimped and a line from the crankcase that was capped. So I reconnected the line, but I need to know what it does. Does it need a check valve? What does it do? Thank you!
