Manuals for Yanmar Diesel Fuel Pumps and Equipment 

Injection pumps are an essential part of diesel engines - delivering the correct amount of atomized fuel, at the right time in the right cylinder.  Robert Bosch invented an injection pump that was simple yet required incredibly accurate machining to work efficiently.

Injection pumps should be kept clean; however, there are no user-serviceable parts and all checks and maintenance should generally be done by a professional injection pump shop.
