I'm hoping to hear back from some wrecking yards soon. This pulley shouldn't be THAT difficult to find...

When you look at the vacuum pumps for the different years the difference seems to be the nipple orientation of the pump.

Another thought, for the people who have changed from v belt to serpentine. Did you change the vacuum pump or just the pulley?
It's not quite the same thing, but here's my experience. I'm currently running a PSD vacuum pump on my Blue truck. It was about $40 cheaper than one for a IDI and I was pretty strapped for cash at the time since I just had to replace the lifters in my recently overhauled 7.3. I can confirm that the nipple is at a different angle. I cheated by cutting the nipple off the old pump and attaching it to the new pump with a short piece of 3/8" fuel line thus making a "double nipple". The biggest issue was that the shaft in the drive unit was a larger diameter on my old pump. In order to get my pulley onto the PSD pump, I had to reuse the drive unit from my old pump. It worked out great for a friend since he had a bearing go out in hid drive unit on hie 95 PSD. I gave him the mew drive unit that I had, he switched them, and it worked great until he sold the truck a few years later.

That may be my thread Regarding using a Dorman pulley. I have no issues with its use. I heated the pulley ithe oven and froze the pump in the freezer and it went right on.

I also purchased a NAPA assembly that has the pump and pulley on it, and have it in the tool box as a spare. Its for a 96+ model also, but works fine. Plenty of vaccuum for the brakes.
Neither pulley has the flange that might guide the belt a little, but it doesnt seem to be an issue.

One note for future readers, get a power steering pulley remover/installer and use it. Tim you got through it. But many have ruined a perfectly good, or worse yet, new pulley by prying/pressing on or off. I am guilty of this too, so learn from my mistake. Buy, rent, borrow a power steering pump removal/installation tool for this job. Cold/Hot thing worked for Tim, perhaps try it, if not get the tool!

I have the Napa 39000 toolkit that works for both vac pump pulley and power steering pump pulley, at least on v-belt setups. It's a little pricey but it has more than paid for itself after using it on 2 vac pumps (1 each on both my IDIs) and one Saginaw PS pump on my RV.

Edit: it's also sold as Lisle 39000 for almost half of Napa's $80 retail price, at least on some websites.

I ended up with a junkyard pump and pulley, so the issue is fixed, for now..... I'm not sure how my old pulley got bent, perhaps I did it with the puller. I dunno. But i do know that I'm going to replace it with a new pump before I go on any long trips with a trailer full of horses! What a PIA this was!
