PTG M177 High Pressure Fuel Pump System
$4,999.99
A complete high-pressure fuel upgrade for the M177. The factory HPFPs run out of capacity well before the turbos do on a built engine, and once rail pressure falls away under load the calibration has to pull timing to stay safe. This system restores the headroom so the tune can deliver the fuel the build actually asks for — the foundation for high-boost and ethanol-blend work.
Fitment
Mercedes-AMG M177 4.0L V8 biturbo
- Direct replacement for the factory HPFPs
- Supports high-boost and ethanol builds
