Default AIR PUMP or NOT?
Should my 73 L48 have an air pump?

Are you asking if it should have it "historically" or if it needs it to pass emissions?

Yeah, if you wanna know whether it came with AIR originally, then the answer is yes.

Yes, All 73 Vettes came with the A.I.R. system.

Yeah, I was asking if it came with AIR? It has long since been removed...still passes WI emissions.

Then you only need one if you want to be NCRS correct. I pulled mine off this year and plugged the manifolds when I installed true duals. It was just extra, unneeded weight.

How difficult was it to remove (unscrew) the air injector pipes in the exhaust manifold? And what did you use to plug the holes?
