300 Straight 6, missing A.I.R Pump..... emission test affected?

Just bought this 88 F150 last week, doing abit of work on the rear end right now, onces it's going to be mobile again, I wanna see if it can pass an emissions test before doing anymore work to it.

It's got 157km (98k miles) of hard work mileage on it.

The air pump is gone, and have no idea how long it's been off.


I have read a long time ago in a thread here witch I can't find again that having no air pump will kill the cats?


If by any chance my cats are still good, can it still pass an emission test without the AIR pump?

It won't kill the cats, but it will throw a AIR system code. My AIR system still works, but I have older heads that weren't made for emissions controls, so I have codes set for that, but the MIL isn't on. My Bronco is also an OBD-I truck.
