5.8L Smog Pump Delete with Pics
Everyone seems to ask this question, but I don't see any picture threads so I thought I'd share what I did on my engine.
I have a 5.8L in a truck that had severe rust damage to the manifolds and air injection tubes. I replaced the manifolds, but since truck is exempt from emissions testing due to GVW I chose to remove the pump and tubes when rebuilding the truck.
Parts that I used:
Proform 68110 5.0/5.8L smog pump eliminator bracket and pulley from JEGS $55
Ford 5.8L AC delete idler pulley $15
Here is the stock air pump.
First I removed the pulley to get to the through mounting bolt.
Mounted on the truck with stock pump still in place.
Pump removed after removing through bolt and back bolt.
Proform bracket installed.
AC delete idler pulley installed.
This combination with the AC pulley allows you to reuse the stock 5.8L serpentine belt with no guessing lengths or dealing with slipping. If you use the Mustang pulley that comes with the kit your stock belt will be too long.
It's just that easy. I left the air diverter valve and solenoids in place on top of the engine and all electrical connections and vacuum lines hooked up. I removed the air tubes from the rear of the diverter valve and manifolds and plugged the rear of the diverter valve to keep dirt out of it. That's it.

As far as I know if you remove the AC idler and bolt on a factory AC compressor you should have no issues. The only problem that could happen is the AC compressor has a different diameter pulley than the AC idler. You'd just have to measure the pulley diameters first to make sure.

pulley?
Greetings, I am slightly confused.
You said not to use the mustang pulley included in the Proform kit, as your stock belt would be too long. I gather that you used the A/C delete idler pulley up top on the driver side of the engine. Which pulley did you use on the lower Proform bracket if not using the included Mustang pulley? A second AC delete idler pulley? Or did I miss something?

Yes a second AC idler pulley on the Proform bracket. The driver's side OEM AC idler has nothing to do with the installation, but I had to replace mine as the original pulley had a bearing that was failing. All 5.8L either come with an AC pump or an AC idler from the factory on the driver's side.

I deleted to remove the air pump as it was starting to make noise and if they seize up then you're dead in the water. The air tubes to the manifolds were also rotted so I was able to eliminate those as well.

AC or AC delete has nothing to do with the air pump removal. (In the pictures I have a new AC delete pulley on the upper left of the motor as the original one had bad bearings.) You do need an AC delete pulley to replace the Proform pulley that comes on the air delete bracket. The Proform part is for a Mustang with a different belt length. You need to replace the Proform pulley with an AC delete pulley on the 5.8L or your stock belt will be too long.

I don't know about the 5.0L, but I think the accessories are layed out differently than a 5.8L

Weight has nothing to do with it. You're knocking maybe 10 lbs off, if that. On a truck that weighs close to 5000 lbs I'm not worried about saving weight.
