if it is efi you will throw a MIL and you gas mileage will go down.
If you can't tell if its efi or not, look for an o2 sensor.
only a carb that is non-feedback? you are good to go, but then why not remove all the emissions stuff too while you are at it.
personally I'd just replace the pump, but there are thousands of trucks on the road that have had them removed, efi or not, and still drive around for years.
I was under the impression that all a smog pump did was pump air in so as to dilute the exhaust and cheat the sniffer. Also MIL?
