Just got 1167 it looks like the valve stems have been removed from my AC lines probably to drain system when decommissioning it... any way to clear the system of dust and dirt or do i need to replace the lines?

Flush backwards from the high and low pressure lines, you can remove the manifold from the compressor and the lines from where they terminat, dirt doesn’t get that far down the lines.

Make dang sure to replace the dryer.
