smog pump

After reading Jeffs reply to this thread,I realized I may have made a mistake in my reply.If I did there would also be a problem with the belt routing that I have on my engine now.I'm running ;water pump,ps.,alt,and the tensioner on top,Its a 1990 engine with the water pump on it for that year.With the setup I have now it is possible to delete the smog pump by simply using a shorter belt.I would like to know why the pump can not be removed without the kit.By doing this I realize that the gap between the tensioner and the belt off the water pump is closer but it will work by finding a belt suitable,(wich took me a few tries.)Everything elese can be removed,and I capped the ports in the back of the heads.If there is something wrong with what I have done here I would appreciate a reply.
thanks.

If you've got a reverse rotation water pump (stock for the serpentine drive motors), and the W/P pulley is riding on the smooth, non-ribbed side of the belt then you're OK. There's more than one-way to skin the cat, you choose one. Some people will even reverse the tensioner spring to pull up on the belt to avoid it being so close like yours. I call these 'mechanic killers' since it makes it dangerous to do anything on the motor with the motor running.
