Re: To much emmision junk on this 79 C10

Somebody had already removed the AIR pump from my 76 that was built for CA.

But they left all those damn tubes so I took them off and plugged the manifolds with a bunch of I think 1/4" PT plugs from the HW store.

I also wired open that stupid flipper valve in the passenger side exhaust because it kept sticking shut.
