I hate screwing stuff up myself
Enough stuff breaks on its own as it is without me helping it along 
. Cross threaded an injector while replacing the fuel returns today. It just did not want to go together on cylinder 6, apparently the line was bent a bit previously as it was tight coming off and popped out when loosened all the way, and I forced it. Leaked after the first startup, backed it off and found a few nice pieces of thread laying there like smileys. Ordered a reman set of injectors from Pensacola Fuel Injection and a #6 fuel line from Midwest Fuel Injection. Expensive lesson to say the least. How will my IP handle the reman injectors? It is not the original IP (Palestine Pump and Injection sticker on it) and the injectors still had grey paint on them and may have been originals

It seems pretty hard to find someone who knows how or is willing to work on these IDI's, let alone not screw something up. "What do you mean it ain't got a computer on it? How do you tell what's wrong with it?"

You'll be fine if you replace the O2 sensor.
Any idea how many miles are on the pump? Recommended change interval at 100k miles. With the new injectors on an old pump you might find a slightly retarded timing as the side effect. Re-time the engine and you should be fine if your pump isn't too far gone.

No idea how old it is, but truck, 89 F250 2wd SC, was sold to me as having 155k with the carfax and wear showing that to be probably true. IP still has a pretty clean shops sticker on its back side, injectors looked like crap, and someone jacked with the return lines at some point changing the routing maybe.

i guess that it would depend on how many miles were on that pump.
im not sure that i would worry about it. if you have to end up replacing the pump youre going to have to be doing that anyway.
like you say it can be tough to find a decent place to work on this stuff. its tough to make money working on old stuff when every bolt head snaps off on you or the truck is just one big hack job.
not sure how much it would cost you but maybe if youre bothered about it the pump could be tested?

I have run those remanned Pensacola injectors on new pumps and old pumps and have never had a problem but I may have just been lucky with that. You can do minor timing adjustment on the pumps by loosening the bolts that hold the pump to the engine and then slightly rotating the pump to the left or right.

Replaced all the injectors and it runs like a champ now. No leaks except where the new pipe is. New pipe + new injector + new cap and viton orings = leak? Only leaks from between the cap's top and the line fitting. It's got me stumped. Replaced the orings and it was the same. I saw mention of placing a 3rd oring between the line fitting and cap to make sure the cap seats better. Anybody ever done that?
