{"replyToPid":0,"replyTo":"","text":"definitely check the governor, I had my pressure safety valve go out, and my secondary tank would not get air. I had to replace the governor and it was $700.The pressure safety valve controls where the air goes, that's how they balance out. And the valve for the one on my truck was not serviceable, had to replace the whole governor."}
