Any 6.5L gurus here care to provide some clarification?
I'm deleting the vacuum pump and going with a spool stick from Leroy Diesel, I was looking at buying the vacuum delete belt from DieselSite, but I saw on a couple different forums you can get a belt from a 93 6.5L, is this true? I'm just trying to make it a little easier on myself when dealing with having to source a replacement; and if I can easily replace a damaged belt via the parts store instead of having to order multiples offline I would much rather go the parts store route.

I'm no guru but I had a 6.5 for a number of years... I deleted my vac pump and put a manual boost controller on it..... without a tune though I could never get it to not throw a code under decent load. I ended up going BACK to the vac pump and vacuum boost control setup, and was much happier with how it performed.

Now if your tuned or something different story, but in my experience, stay with the stock setup, it just works better, even though you have to have a dumb fail prone vacuum pump - I originally deleted it because the pump seized. They aren't terribly expensive (or werent)... just plan to replace every few years, maybe when you do new belt.

I'm going to spring for a tune in the future in addition to a few other upgrades, but for now I'm just going to do the old trick with a 10K resistor soldered in line from the MAP sensor, it functions as a boost fooler. That along with a #9 resistor on the PMD, I'm hoping that the truck will run pretty decent set at 10-12 PSI. Full gauge set too, I don't want to cause anything to go disco inferno

I debated on just replacing the vacuum pump, but I do plan on an HX35 swap down the road a ways, so I just decided it was a necessary evil to delete the pump once and for all. The 6.5L probably won't be in this truck forever either.

Guess what I found on Marketplace late yesterday? '97 ecsb K2500 8 lug, 6.5, NV4500, NP241 rig. If it wasn't $3500 and an obvious electrical nightmare, I think I'd try for it once my new job gets situated.

I would  like to get it and rebuild it. But that's above my current space and skill limitations.
Understandable; I lucked out with my truck being relatively put together from the salvage yard, that one looks a little more gone than my truck.
And no title? Oof, that's a deal breaker for me, my days of fooling with no title trucks are behind me once the crew is situated

It's reasonably easy to fix the title situation in Texas. Bonded title, and after 4 or 5 years, it gets reissued as a standard Blue title.

Alternatively, I could try the Vermont loophole.
