Compatible MerCruiser Engines

Designed for MerCruiser sterndrive and inboard engines with Gen III Cool Fuel systems (2004 and newer).

Common engine applications include:

MerCruiser Sterndrives / Inboards

• 5.0L MPI

• 350 MAG MPI

• 377 MAG MPI

• 496 MAG / 496 MAG HO

• 6.2L MPI

Function

The Cool Fuel module supplies and regulates fuel pressure while cooling the fuel before it reaches the engine’s injectors. This helps prevent vapor lock and ensures stable fuel delivery under high engine loads.

Replacing a worn or failed fuel module helps:

• Restore proper fuel pressure to the EFI system

• Prevent engine stalling or hesitation

• Maintain proper fuel temperature and cooling

• Ensure reliable engine performance and starting

Important Compatibility Note

Fuel module kits vary depending on engine model, fuel system generation, and serial number range. Always verify compatibility using the engine serial number before ordering to ensure the correct fuel module kit.
