The air pump was last used on '82 model 258s. The 2 hoses from the switching valves go to the underside of the aircleaner. If you have an older model air cleaner, you will have to add the fittings, roughly 3/4"od tubes. Your Jeep would visually fail a CA emissions test as it is considered "modified". If your state isn't concerned about visual inspections, I'd leave it alone, as the pulse air system tends to blow exhaust,rust and carbon into the aircleaner housing that plugs up the carb jets, when they fail. The smog pump takes very little power to run. Hope this helps, good luck!
