About two months ago I took my smog pump out of the belt equation because the bearings were shot and it was squealing like a stuck pig. I was under the hood yesterday and noticed that there are two hoses going from the smog pump to a juice can (figuratively speaking). If I remove all that will I have any problems besides smog issues with concerned state officials? I live in TX and they don't require any kind of emissions test. I want to tidy up under the hood and get rid of the stuff that I have disconnected and no longer use. If that pump and hose combo is going to cause poor performance then I will reconsider but if not it needs to go. Thanks in advance.

when i bought my truck the belt was already off the pump. when i had the motor overhauled i had all the emissions equipment pulled off and the holes plugged up. i live in ND so it doesn't really matter. pickup runs just as good without it, if not better. there is also a lot more room under the hood.

I didn't want to make changes to the belt system mainly because of the time that I had.

I am not 100% sure but I bet that with the smog pump removed, those 2 lines don't do anything but like I said, I am not sure. Don't remember any senors etc... from the "juice can".

 

[updated:LAST EDITED ON 02-Dec-02 AT 06:38 PM (EST)]The smog pump injects fresh air into the exhaust just above the valves and again in front of the cat. but behind the O2 sensor. There is a computer controlled module that determines how much fresh air is injected and to which point. This introduction of fresh air helps the catalytic converter burn off additional crud by adding some oxygen to the exhaust mix. Not certain what effect removing the pump would have on O2 sensor(s) One thing to be certain of, if you remove the pump (and subsequent hoses etc.) is that the check valve(s) that keep exhaust from backing up into the air injection hoses are in working order. This is more a safety thing than anything else. On EFI 302's and 351's there is one at center behind the intake (right above the top of the bell housing). I had that one pop in half and the exhaust backed up through it and melted part of the main wiring harness and several vaccuum lines.

This info is based on my personal knowledge of 92+ Broncos. Earlier years may have different setups but the introducion of fresh air via the smog pump into the exhaust is constant for any vehicle that has one. My '69 Caddy had a smog pump and the air was introduced into the exhaust at the heads just above the valves.
