Hey everyone, so recently I've noticed I been leaking fuel only when I'm driving at highway speeds. but when I drive in town nothing really happens. I check the cp3 lines and injector lines and they look good. Its starting to become a headache cause I cant find the issue. has anyone had this problem before and point me in the right directions so I can fix this. its and 2004 Cummins High Output 5.9 with no fuel modifications and I jst had injectors replaced.
