Air pump/smog pump question March 27, 2013, 10:43:34 PM On the late 80s 302 efi engines they have an air pump on the passenger side being driven by the serpentine belt. This pump probably creates a lot of drag so is there a way to pull it out? Like putting a smaller belt on or does some aftermarket brand sell a eliminator for it? Or should I just leave it be instead of going through that hassle? Quote Selected

Air pump/smog pump question Reply #8 – March 28, 2013, 12:14:43 AM You can bypass the belt without removing the smog pump, just get a shorter belt. The smog pump is almost just a pulley to begin with. I don't get why people buy the eliminators. Quote Selected
Air pump/smog pump question Reply #9 – March 28, 2013, 07:22:26 AM What about the tubing going from the exhaust to the pump? There are wires connected to it and I think they are sensors Quote Selected

Air pump/smog pump question Reply #11 – March 28, 2013, 09:02:22 AM I dont have cats either so i dont have to worry about clogging anything in the system. If i eliminate the pump does the car recognize that it has been taken out? Quote Selected
Air pump/smog pump question Reply #13 – March 28, 2013, 10:06:33 AM I would suggest that you get the plugs that go in the back of the heads as this will allow you to remove the tube assembly and get you more room to work on that side of the car. The wires that you said you are seeing going down to the exhaust could be for the O2 sensors so definitely figure out what those are before you go removing them. Cut the tube going from the O2 pump the the exhaust about 3" to 4" from the exhaust pipe and cap it. If you can weld it shut that is better. I took mine out of the car and had an exhaust shop weld it shut. They would not do it here with it on the car as it qualified as emissions modification which could get them in trouble. I completely respected their position on it and asked if I could pull the X-Pipe out and bring it to them and he was totally cool with that.Darren Quote Selected
Air pump/smog pump question Reply #14 – March 28, 2013, 04:53:27 PM I gutted my pump. Just broke the plastic blades off. All that remains is the housing,pulley and bearing. I had bought a air pump eliminator pulley, but it didn't fit. The pulley was the wrong size. The gutted pump worked perfect as a pump eliminator. As Aerocoupe said, after that, you can plug the back of the heads and eliminate the tube assembly. Quote Selected
