Mercedes-AMG GT M178 Spool FX-200 High Pressure Fuel Pump Kit

The Spool FX-200 high pressure fuel pump kit for the Mercedes-AMG GT M178 adds roughly 80% more flow than the stock pump, so the M178 can support bigger turbos and higher ethanol blends.

Why you need it

The stock high pressure fuel pump on the M178 is the first fueling limit you hit when tuning. The FX-200 uses a bigger bore than stock for roughly 80% more flow, can run pressures up to 240 bar for more injector output, and is fully E85 compatible.

Fits

• Mercedes-AMG GT, GT S, GT C and GT R (M178)

What's included

• 2 x Spool FX-200 upgraded high pressure fuel pumps
• Bosch-spec 10-micron high-flow fuel filter

Spool 10-micron filter

The included filter unit protects the high pressure pumps and injectors from debris without a noticeable pressure drop on the low side.

Good to know

Choose at checkout whether to add the ethanol analyzer or use one you already have. The added fueling is used through a tune. Professional installation is recommended.
