I have a 92 super duty, the truck only has 41k original miles, so I had a leaky return line on one of the injectors. Replaced all the return lines and caps on the injectors along with new orings . Now I have a noticable miss. Cracked all the injector lines, and all change the engine. I dont see any leaks on or around the return lines and am at a loss.
