Engineered Marine Products 1399-39024 Fuel Injector Crush Ring Kit

The Engineered Marine Products (EMP) 1399-39024 Fuel Injector Crush Ring Kit provides the sealing hardware needed to properly seal fuel injectors during service or replacement on marine multi-port fuel injection (MPI) systems. Crush rings — also commonly referred to as injector inlet seals or copper sealing washers — form a leak-free metal-to-metal seal between the fuel injector and the intake manifold or fuel rail mounting surface, preventing fuel leaks and maintaining proper fuel delivery pressure.

Key Features:

• Replacement crush ring sealing kit engineered specifically for marine MPI fuel injection applications
• Restores a proper fuel-tight seal at the injector mounting interface
• Manufactured to meet demanding marine environment standards for durability and corrosion resistance
• Essential service component when removing, replacing, or resealing fuel injectors
• Engineered Marine Products (EMP) brand — a trusted name in marine OEM-quality replacement parts

This kit is a necessary maintenance item any time fuel injectors are disturbed during service. Reusing old or deformed crush rings can result in fuel leaks, rough idle, and loss of fuel rail pressure. Always replace crush rings as part of any injector service procedure.
