Yes, you should be able to leave the pump on and just route a shorter belt around it. Your cats, if you have them will wear out faster without the smog pump working.

Nothing...just lost 5 pounds worth of junk.


Smog equipment doesn't rob as much HP as your think. In fact..i don't beleive it robs any.

well if you don't have cats, there isn't much point in keeping the pump on there. you'll maybe gain 0.5 hp by removing it, but it weighs quite a bit, and really cleans up the engine when its gone. you don't plug the lines, just take them right off, then plug the heads. it is all very easy to do, so don't worry about that.

looks like hell, adds weight I'd just bypass it w/ a belt and be done w/ it.

I think I used a 82.5" belt with power steering an a/c to bypass mine, I have the belt in the garage I'll see if the part number is still readable tomorrow.
