Air Questions, 96 FLD 112

Hey guys,

I'm currently in the process of prepping my 96 FLD112 to go over the road. Working out little quirks.

I've got a question on an air issue I've got. I stumbled across two lines coming out of the firewall into the engine bay... right under the drivers side windshield wiper. One is a yellow air line, the other looks like a vacuum line. They're cut clean. The yellow line will push out air with the parking brake off, but will cut off when you pull that yellow knob. The parking valve will not pop out even when the air is fanned down to zero. I'm assuming these issues are connected, but I do not have enough experience with FLD's to figure out the issue. Does anyone have any info that can help me out? Pressure holds at 120, and doesn't seem to cut out/on any more then the Columbia I tested in.

I also have two air leaks involving my A/C. Both air rams that operate the different flaps/valves leak, at the fitting. Can I pull these fittings without breaking them, recut the line, and reassemble? I can't seem to get them out... so are the brass fittings a one-time-use type of deal?

Any help would be appreciated.

Thanks
