Product Details

The Sierra 18-33207 is a replacement fuel pressure regulator engineered for MerCruiser multi-port fuel-injected (MPI) marine engines. In an electronic fuel injection system, the fuel pressure regulator maintains consistent fuel pressure in the fuel rail, allowing additional fuel to flow to the engine as demand increases — ensuring proper fuel delivery through the injectors under all operating conditions.

This Sierra regulator mounts directly on the fuel cooler and is built to meet or exceed OEM specifications, offering a reliable, marine-grade alternative to the original MerCruiser part.

Key Features:

  • Direct replacement for OEM part numbers 860349A1 and Mallory 9-33207
  • Mounts on the fuel cooler for straightforward installation
  • Designed for MerCruiser MPI multi-port fuel injection systems
  • Built with marine-grade materials for durability and corrosion resistance
  • Backed by Sierra's comprehensive parts and labor warranty

Part Number Cross-Reference:

  • Sierra MPN: 18-33207
  • Replaces MerCruiser Stern Drive: 860349A1
  • Replaces Mallory: 9-33207
