Modalworks is proud to present its upgraded Dual Low-Pressure Fuel System (LPFP) for the Mercedes-AMG M177 platform. This system offers a robust solution to the limitations of the OEM single pump. Designed to handle the increased fuel demands of high-horsepower setups, especially with E85, it features a dual-pump configuration that significantly enhances fuel flow.
The upgraded system includes a secondary pump that activates under boost, nearly doubling the fuel flow capacity compared to the stock single pump—delivering ample fuel for power levels exceeding 1200whp. The Walbro F90000285 (Walbro 525) is at the heart of the system, a high-performance pump designed to provide superior high-pressure fuel flow. Built with OEM technology, it’s designed specifically for E85 use, meeting all standards for performance and durability in E85 and flex-fuel environments.
The kit includes the following components:
- OEM fuel pump assembly with a professionally installed secondary pump, featuring high-quality lines, crimps, and wires, all fully compliant with E85.
- Wire harness assembly with a Hobbs switch to activate the secondary pump during boost for efficient fuel delivery under high load.
- An optional boost tap and vacuum line kit are available for easy installation of a boost reference source for the pump switch.
THESE KITS ARE CURRENTLY MADE TO ORDER AND CARRY A LEAD TIME OF 5-10 BUSINESS DAYS BEFORE SHIPPING.
