Fuel Cooler – Mercury MerCruiser

The Mercury MerCruiser fuel cooler is designed to keep your fuel temperature stable, protecting your engine’s performance in all conditions. By cooling the fuel before it reaches the combustion chamber, this part helps prevent vapor lock, improves efficiency, and ensures consistent fuel delivery.

Built from high-quality marine-grade materials, it resists corrosion and lasts for years in harsh saltwater or freshwater environments. The cooler’s robust copper and brass construction handles marine heat cycles without warping or weakening. It fits a range of MerCruiser inboard and sterndrive models, making it an ideal OEM replacement.

Easy to install, this cooler connects directly into the fuel system and integrates with the existing cooling loop. It’s a critical component for anyone running high-load, high-performance marine engines—whether you’re cruising long distances or towing heavy loads.

Benefits:

• Maintains optimal fuel temperature for better engine health

• Reduces vapor lock and fuel boiling risks

• Improves fuel system reliability under load

• Built from corrosion-resistant marine metals

• Direct OEM-style fit for quick installation
