Engineered Marine Products 1300-00112 Fuel Pump Repair Kit for Mercury Mariner Outboards

The Engineered Marine Products (EMP) 1300-00112 is a fuel pump repair kit engineered for Mercury and Mariner 2-cylinder 35 HP and 3-cylinder 60–70 HP outboard motors. Covering model years 1977–1980, 1982–1987, and 1989–1990, this kit provides a cost-effective alternative to full pump replacement, restoring proper fuel delivery and reliable engine performance.

Key Features:

• Direct replacement for Mercury OEM part numbers 55278A4 and 55278A3
• Cross-references with Sierra 18-7809 and GLM 40340
• Designed for Mercury/Mariner 2-cyl 35 HP and 3-cyl 60–70 HP outboard fuel pumps

Over time, fuel pump diaphragms can develop cracks or pinholes that disrupt proper fuel flow, and internal check valves and springs can fail, leading to complete pump failure. This EMP repair kit addresses these common failure points, allowing for a straightforward rebuild rather than a full pump replacement. It is a reliable, direct-fit solution for maintaining the fuel system integrity of compatible Mercury and Mariner outboard engines.
