Default A.I.R Pump Elimination

1986 C4 smog pump seized and fell off while driving. Can I get the delete kit installed so the serpentine belt runs without removing any lines or plugging the manifolds (basically just remove the smog pump next to the alternator)?

Pull off all the plumbing, cap off the 1 way valves with pipe cap from Home Depot, put a plug at the cat where the AIR pipe goes to it so road debris doesn't get in.

Anytime. Take the valves off so you can get the pipe cap at HD or whatever store you prefer. Don't tell the smog ***** or we'll both be shot at dawn.

Perhaps but there is going to be someone that carps about "You are causing me cancer" when you talk of eliminating emissions stuff.

Just did mine. Pipe cap is a standard 1/2" threaded pipe cap.
