Progressive Air balance kit troubleshoot

[bobhamlin]

I just purchased and installed the kit. After losing pressure, I used soapy water to trace the leak to the attachment that comes out of the head. (The base of the part to which you attach the airhose.)

It looks like a small hex bolt. The air is escaping between this bolt and the head. Since it was factory installed, I'm leery of trying to tighten it.

Is this something I should try? Or contact Progressive for a replacement?

Thanks,
