If you think it's the injector and it well could be, put two units of Texron injector cleaner to 10 gallons of real 100% gas. This is the first step in finding the problem.

I think it's more than a simple cleaning. If his truck is sitting and the plugs are getting wet, then that means that the injector is not closing all the way when off. No cleaning solution is going to really solve this. Either bench clean and test the injector or get a new one. I had this happen to me on a 5.9 Grand Cherokee that I had and let it go too long. Ultimately it caused serious issues in the end that I could avoided if I had done what was right sooner.
