When I said leaking injectors will lower fuel pressure, I didn't mean the injector seals, I meant nozzle.
The injector seals used with the LH systems last a long time in my experience, approaching the life of the car. I used to occasionally need to replace the injector seals every few years in my K-Jet, but not yet on any the LH-Jets I've worked on. I'm sure you know the trick about spraying water around the the base of each injector while it's running to see if it makes any hint of change in idle.
