The JDY S58 Low-Pressure Fuel Pump (LPFP) Upgrade Kit is an integrated, high-flow fuel delivery solution engineered with Walbro Fuel pumps on the BMW S58 platform. Developed to support higher power and boost levels while maintaining OEM-grade reliability, this system upgraded from the restrictive factory LPFP module with a precision CNC-machined 6061-T6 aluminum assembly housing a high-output Walbro 450 (F90000274) or Walbro 525 (F90000285) in-tank fuel pump. Key Features 1. High-Integration Design JDY¡¯s LPFP integrates the additional Walbro pump directly within the factory fuel pump module using a CNC-machined billet aluminum fuel rail . All external lines, fittings, and the fuel pressure regulator are built into this module and connected via PTFE hoses with quick-connect fittings , eliminating leak points, providing easier service, and superior reliability under high load. 2. Reusable Stainless Fuel Filter System At the bottom of the factory pump lid, it features a stainless-steel Micron fuel filter , allowing easy service and reuse, eliminating the issue of clogged non-serviceable factory filters. This upgrade extends system life and ensures consistent fuel flow for customers focused on performance and long-term reliability. 3. Stage 3 ready A dedicated return line port is pre-machined into the housing for enthusiasts planning a returned fuel line setup with an external fuel pressure regulator. The port is pre-plugged for stock configuration, enabling a seamless upgrade later without replacing the entire assembly. 4.
