Working on diesels for a living I have had injectors that tested "good" but if I'm building an engine or working on a customers machine their gonna be rebuilt if their not right. Whatever the cost, having the injectors right and knowing it, is a small price to pay vs the the customer having a problem with the engine after I leave. I may know that a "good" injector is OK to use and many people understand exactly what's going on in their engine and would understand that too BUT typically there's a serious lack of knowledge and all they know is how to start and run the machine. That lack of knowledge is what's dangerous to those of us in the business because their not understanding automatically makes any problem fall right on my shoulders. In that case it's not so much about the liability as it is the customer only knows you worked on his machine and then he still had problems after you left. We all know a "bad experience" will get more talk time to his buddies than a good experience, and that in turn leads to a bad reputation for the man that did the job even though it's underserved because it was created by an unknowledgable customer and not something actually done wrong. That said, "Bad" injectors and tractor not running don't always go together. "Bad" injectors be anything from it leaking, a bad spray pattern, worn internals,worn tip, low popping pressure because of one of the above, etc, etc. This can can cause all sorts of things from excessive fuel usage, excessive smoke, hard starting, uneven wear on engine parts, holes burned in pistons, etc etc etc. In the case of a fuel shop, their i the same boat I'd be in whe it comes to the customer. An injector has a certain spec range it should be in and it's their job to put the injector within that range for the customer, unless you specifically tell them not to. Thing is most customers aren't knowledgable enough to tell them that their injectors are "good enough" to run (or they wouldn't have taken them to the shop in the first place) so it's left up to the shop to make that judgement. Once again if the engine has problems after the the injectors leave the shop then the liability and bad rep is gonna get laid on the shop, not the customer that told them not to repair them. Look at it like this, do you usually take other things to a repair shop and tell them to "fix it half" way and that'll be good enough? Injectors are the same way,if they don't check to spec a fuel shop is gonna fix them right, or not at all, unless you specifically tell them not to. Yes there may be miscommunications at times that wind up costing someone alot of money and though there was a miscommunication, the shop was simply doing the job right to cover their rears. Believe me I've dealt with the same guys for enough years I've heard the horror stories of the things blamed on them I know where their coming from. In the end it all comes down to an old saying,"if a job's worth doing it's worth doing right". All these guys are trying to do is to do their job right...
