C63 Spool FX-200 upgraded high pressure pump kit (M177)

The FX-200 is an upgraded high-pressure fuel pump. The pump features a bigger bore size than stock that translates into roughly 80% more flow when compared to stock. The pump is completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos.  The pumps are also capable of running higher than stock pressures up to 240bar which increases fuel injector output and also reduced injection time.

Why do you need it

The stock HPFP on the M177 Motors is severely limited in capacity when trying to tune and raise the output of the motor. The FX-200 adds 80% more flow to the equation, raising the fueling limits on the platform and helping you run bigger turbos and/or higher ethanol concentration blends.

***Low Pressure Fuel Pump Upgrade Requirement

Due to the higher flow requirement of the FX-200 HPFP, Spool highly suggests upgrading the Low pressure fuel pump as well to avoid any starvation issues with the upgraded HPFP. If customer chooses to forego the upgrade of the low pressure fuel pump, and damage from low pressure fuel supply issues occurs, the purchase of the FX-200 HPFP would be excluded from any warranty coverage.

Spool 10-micron filter unit

Our 10-micron filter unit boasts the best filtration available Mercedes market without any noticeable pressure drop in the low side fuel system. The filter unit helps keep the high-pressure pump and injectors safe by protecting them against debris and is highly recommended.

Spool Ethanol Content Monitor

The spool ECA kit  features a digital readout of in-tank ethanol content and fuel temperature. It includes our SPOOL Ethanol content analyzer app on mobile and readouts are delivered via BLE 4.0 low energy technology. BLE4.0 allows you to use your regular Bluetooth devices on your mobile devices while being connected to the SPOOL ECA module. Fuel lines used in the kit are braided steel nylon core fuel lines that are 100% E85 compatible.

Are tune changes required?

The upgraded pumps do require calibration changes. It is important to apply these changes prior to starting the car with pumps installed to avoid any possible damage and void of warranty. Our ZAC OPTIMUM tuning by Morendi is highly recommended.
