As the relevant rules are mostly unchanged, my contention remains that assuming you can bypass part quantity limits to install a spare (this is clearly past and present practice regarding motors, for example), there is uncertainty as to whether air already legally stored in the tanks ceases to comply with R68, and thus R24.

Basically: if you are entitled to bypass the R68 limit of 1 to install a spare compressor, what necessarily prohibits you from bypassing the same limit as a result of the same act to use the air supplied by the first one? It's the same clause of the same rule, and yet to prohibit the air would be to enforce and overlook it simultaneously.

How would you replace a compressor without dumping the air first? Sure, it's possible with an off board compressor, but an on-board one, which covers probably 99% of the compressors I see at competition...
