The XDI-EVO high-pressure fuel pump set from Xtreme-DI is the fueling backbone for serious M177 / M178 builds. Once you push past bolt-on territory, the factory Bosch HDP5 pumps become the ceiling — the XDI-EVO raises it with 36% more geometric capacity than stock and up to 250 bar of rail pressure, keeping direct-injection fueling stable under E85 blends, big turbos, and aggressive tunes.
- Set of 2 pumps — direct replacement for OEM Bosch HDP5 (A1770700501 / A1770700401)
- Up to 250 bar (3,600+ psi) rail pressure capability
- Plug-and-play with OEM feed lines; self-centering base plates, adapter looms, and hardware included
- Optional upgraded high-pressure line kit available — select the package option above
