my 97 has 205,000 miles on it, I think it has AB injectors. I bought AA with 85,000 on them. Will these work in my truck? I'm thinking about diy stage1's in the spring. Should I use the AB's if the tolerances are good and save the AA's for a rainy day or possiable stage2's in the future or just use the AA's? I'm also thinking about doing a 17*hpop upgrade. What year 7.3's are these on and is it worth it?

I'm thinking ab s are the 120cc splits only on the cali models, don't know for a fact though. If you have single shots the aa will be fine. If you have splits now you will need different programming to run the splits properly I think. The only was you would have splits in a 97 though is if its a cali. Easy ways to tell is the fuel pump has a big pulsation damper on it making it look like the starship enterprise(no joke, really does). And the sticker on the rh valve covers of the cali models has a blue background instead of black. Being in michigan its possible for you to have a cali truck, but unlikely.

As to your question about the 17* pump. It's only going to sheer/breakdown your oil faster, than your stock pump.
It will pump more volume. The only real reason to need more volume is you putting in bigger injectors.
If I've understood all I've read on it, up to stage 1's or hybrids, the stock 15* pump is pretty sufficient. Stage 2's and up, you'll need/want... 17* pump or aftermarket dual pump setup.
What are your plans with the truck? Daily driver, towing, or competition.
If your AB's aren't within specs, they can be machined to bring them in line.

the fuel pump looks like a normal diaphram pump with two hose fittings on top and the sticker on the valve cover has a black back ground. So it should have AA's right. As far as puting stage ones in the 205,000 injectors would thay be ok if thay pass the tolerances on the diy website?
daily driver mostly/ pull a 8000# fith wheel 5x a year/ fourth of july truck pulls. As far as the machining I work in a tool and die shop as a machinist so any grinding or turning I should be able to handle once I take one apart and see how thay tick.
