Re: Remove AIR from 1999 Z28
Don't have an LS1, but have the 1998 and 2000 factory manuals. They both show the same system, and indicate the AIR pump is bolted to a bracket on the drivers side front frame rail. Instructions appear fairly simple:
1 - Raise vehicle
2 - Remove driver's side lower closeout panel
3 - Remove hoses from pump
4 - Disconnect electrical connector from pump
5 - Disconnect electrical connector from bleed valve solenoid
6 - Remove 3 AIR pump bolts from mounting bracket
7 - Remove AIR pump.
Did you remove the AIR pump shutoff valve?
