WTF do I do with the old smog pump lines?

I have an 84 Ranger with a 2.8L V6.

The last owner took out the cat and left the tube going from the smog pump just sorta hanging there. I live in a state & county where there are no emissions tests or anything like that.

I decided to take out the smog pump but now I'm not sure what to do with all the old lines going from the exhaust manifold and the carb. Used a PS belt to connect the alternator to the flywheel... I think I can just plug the exhaust pipe lines, but what do I do with the vac lines (I think?) going into the carb? Isn't the EGR also on this exhaust line as well?

I heard that removing the smog pump will cause the engine to run badly, since the on board computer somehow adjusts the carb based on vacuum or something along those lines...

Anyone have any ideas? What should I do with the old tubes? Does the carb need to be swapped out? :icon_confused:



Edit: the truck is like a $400 POS and I'm broke, so I'm trying to avoid getting a new cat... I just wanna drive this baby.

You should replace the cat and exhaust, and hook everything back up correctly.

Is there a way to get it working well without having to buy a new cat?

Not as well as stock.

Also, it's a violation of federal law to disable emissions control equipment, regardless of whether your area requires emissions inspections.

Hmm... Let's say I'm using a cat that doesn't require air to be injected. How would one go about removing the pump then?

In all seriousness, I really cannot get a matching cat yet but I will be getting it near stock soon.
