No Air-Pump. What else can go?
 

So my car has been without an air pump for some time now but everything else is still hooked up.

My car is an 84' SE with rb headers and aftermarket air intake.

I was wondering what else associated with it is unnecessary at this point. I'm not to sure what else I can get rid of without messing with the operation of my vehicle.

Does anyone know what parts of the system I can get rid of?
