Good morning. I have recently acquired a 1975 Chev C10 with a 350 4bbl. The truck is completely stock for the most part. I am going to start removing some of the emissions crap on it as where I live there are no emissions laws (Canada). I have looked into removing the EGR and blocking it off, as well as, the smog pump and I understand how to do those. My question is what the heck is this thing?? I also noticed that there is a bracket right beside the smog pump that has nothing attached to it...I'm assuming the smog pump was bypassed however all the hoses etc are still there including the metal lines attached to the stock exhaust manifolds. Thanks!!
