A.i.r. Fuse

[LowRyter]

I just checked my underhood fuse box on my 1999 Chevy 2500 6.0. I was looking for the trailer power fuse (I found it).

 

One fuse that is missing is labeled as A.I.R. I am not sure what it is, what fuse is needed in that slot and whether or not I should install it.

 

Any help is appreciated.

That is for an emission related air injection pump, and you truck probably does not have it, that is why there is no fuse.
