Mechanical fuel lift pump for Massey Ferguson tractors and industrial equipment running Perkins AD3-152 and related three-cylinder diesels — the 35, 135, 150, 230, and 235, along with MF industrial and backhoe variants. Inlet at the 3 o'clock position and outlet at 2 o'clock with the cam lever facing you, two-bolt mounting on the standard Perkins block pattern. Gasket included. The diaphragm is the known wear item; it stiffens or cracks with age, and fuel delivery to the injection pump drops before the pump fails outright — typically showing up as hard starting hot, or the engine stumbling under draft while idling fine.
