When doing recent servicing the injector pumps on the twin Lehmans on my CHB trawler, I found thin oil when draining one of them. This was the first service I’ve done on them since owning the boat. Is it possible that fuel could be getting into the oil reservoir on Lehman 120 HP six cylinder engine injector pumps? There is such a small oil reservoir in these pumps, I find it odd that one of them had thinner oil in it than the other one.
