Sierra 18-33211 Fuel Pressure Regulator, Replaces 860349A1, Fits MCM/MIE 7.4L/LX MPI, 4545 Mag MPI, 502 Mag MPI, MIE 8.2L MPI

The Sierra 18-33211 Fuel Pressure Regulator is a direct-fit replacement regulator that mounts on the fuel cooler of compatible MerCruiser MPI engines. It maintains fuel delivery within a measuring range of 43.5 to 58 psi and produces an electrical output signal for the engine management system, helping keep fuel pressure steady for consistent engine performance. The regulator is constructed of metal for durability in the marine engine environment and is built to the same specification as the original equipment it replaces, cross-referencing to OEM number 860349A1.

This regulator is designed to fit MCM/MIE 7.4L/LX MPI, 4545 Mag MPI, 502 Mag MPI, and MIE 8.2L MPI engines, and mounts on the fuel cooler. It is a straightforward swap for boat owners and marine technicians replacing a worn or failing fuel pressure regulator on these MerCruiser MPI powerplants.
