Engineered Marine Products 1300-03751 Manifold Absolute Pressure (MAP) Sensor for Marine EFI Engines

The Engineered Marine Products (EMP) 1300-03751 is a direct-replacement Manifold Absolute Pressure (MAP) Sensor engineered for marine EFI applications. The MAP sensor plays a critical role in the engine management system, continuously monitoring intake manifold pressure and relaying that data to the engine control module (ECM). This allows the ECM to calculate precise air-fuel ratios for optimum combustion efficiency and performance on the water.

Key Features:

• Direct OEM-style replacement MAP sensor for marine GM-based EFI engines
• Monitors intake manifold absolute pressure for accurate air/fuel mixture control
• Works in conjunction with the throttle position sensor to support the engine control module
• Engineered to marine-grade standards for durability in harsh on-water environments
• Plug-and-play fitment — no modifications required

Engineered Marine Products (EMP) is a trusted manufacturer of high-quality replacement sensors and electrical components for inboard marine engines. The 1300-03751 MAP sensor is the ideal solution for restoring proper fuel management and engine performance when the original sensor has failed or degraded.
