What you should do is invest in an inexpensive battery tester (Radio Shack has them, Walmart might have them). Then you can test your batteries periodically (a couple of times a year if you wish). As long as they're showing the proper voltage there's no need to replace them.
Q:Fluid Flow through Straight pipe and pipe fittings? Urgent!!?
Maybe you can run in a temporary line from the compressor, connected to a branch with a valve. You will have to shut down whatever is on the other end until the connection is made, unless it has a valve fitted for this purpose. Another idea is to get a portable compressor or hire one for temporary use.

most everything burns a different color. people are used to seeing wood burn (campfires, etc). there are all sorts of chemicals that all burn different colors. a household example is natural gas (stove) burns blue. i would imagine that the rubber or to an extent, the chemicals in the rubber hose burn that particular color.
