Where are Engine-Mounted Fuel Filters (EMD) located on locomotives?

• A. Right-hand side of engine
• B. Under the radiator
• C. In the fuel tank
• D. Left-hand side of engine

Answer: (D)

Engine-mounted fuel filters are attached directly to the engine so fuel is filtered just before it reaches the pump and injectors. On many EMD locomotives, this filter assembly is placed on the left-hand side of the engine, which provides convenient access for maintenance and keeps the filtering close to the fuel supply path without routing extra long lines. The other options would involve different system layouts—placing the filter on the right side, under the radiator, or inside the fuel tank—and would not align with the typical engine-mounted arrangement. Therefore, the left-hand side of the engine is the standard location.
