I just took the pump out("adjusted" bracket at later date) then bought a shorter belt. Let me see if I can find what size that was. It should be able to find in a search here. Good luck. keep posting on your results.

you can delete the air pump without doing anything except get a new belt.

Hope this helps, if you have not already figured it out. This is an old post of mine is a different thread.

I don't know how old this thread is, but I'd thought I'd throw my 2 cents in since I wanted to eliminate my noisy Smog Pump. I have an 84 with the dreaded Crossfire Injection. I went to Summit Racing, and they had a bracket that I would have gladly paid the almost $60 for, but it had the wrong pulley (I needed the one for the grooved side of the belt, the pulley on the eliminator bracket was for the smooth side of the belt). So after looking at it for a bit I decided to try and take the Smog Pump out of the bracket, and get a shorter belt. The car comes with an 88 inch belt, and I put an 84 inch in it's place. It was kinda tight (I had to pry it on) before I relaxed the tensioner onto the belt, but when I did, it still took up a little slack. After I test ran the engine, I fabbed up a small block plate that goes over the hole on the tube that attached to the Pump itself. It isn't pretty, but it works. Total cost for a replacement Pump, about $90 from Auto Zone. Total cost for my solution, just under $25 from Auto Zone for a new belt, plus the scrap piece of aluminum I had in my garage. I think if I had it to do over again, I'd opt for the 85 inch belt, since it would be easier to put on. The belt routing is the same as it was, just now there is no Smog Pump to go around. And I wouldn't swear to it, but I think the car is running just a little better now, or maybe it's just my mind playing tricks on me. Either way, I no longer have a noisy, metal on metal squeaky, worn out smog pump on the car.

Sounds good. Was contemplating this when I had my smog pump lock solid while on the road. It took out and fried a fairly new serpentine belt and sprayed burnt rubber everywhere in the engine compartment! I had to make a quick repair "in the field" and had to get a refurb'd pump from Advance Auto (about $90) and a new belt, so I put the conversion on the back burner for now. Any error message codes pop up due to the removal of the pump and the related relays/harness?

Nope...

all you need is a shorter belt.....

thanks for the belt size good info I knew some one on here would know.....

There are actually 2 belt sizes that are used. some work for some folks better than the other. Mine fit perfectly on first choice but the next car it may not. I think I used twine to get a measurement. Variable is the tensioner.

If you want to delete the ac compressor too, order a dorman 34157 delete kit for 88-92 f bodies and use a goodyear 4060872. 87.2" belt. Sure cleans up the engine compartment!
