Hi All have a Lehman 120 and for the life of me cant find the drain plug to change oil in the injector pump, and it seems like such a critical service item relative to longevity of pump, by other photos provided by owners of lehman 120 my injector pump looks different mine has a hose going from the top of the oil filter to the injector pump which i suppose puts engine oil into the injector pump and making the need for oil changes redundant and unnecessary
Thanks in advance for any advice
Michael
