Why do you need it
The stock HPFP on the M157 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.
What does the kit include?
2 x FX-200 upgraded high-pressure fuel pumps
1 x Ethanol Content Monitor kit with mobile app
1 x Bosch spec 10-micron high flow Fuel Filter
Upgraded Fuel lines and all necessary install hardware
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.
Spool Performance can provide calibration details to your existing tuner and/or help you connect with established tuners who are experienced with these pumps. Custom tuning is required to get maximum output out of the upgraded pump setup for your specific vehicle setup and ambient conditions. Spool Performance is a hardware manufacturer and does not provide custom tunes, but can assist with questions your tuner may have.
Low Pressure Fuel Pump Upgrade:
Proper low pressure fueling is extremely important for proper functioning and durability of the high pressure pumps and injectors in a DI system. Inadequate low pressure fueling can cause damage to the pump piston and bore as they are lubricated by controlled leakage of fuel. Resulting damage from low pressure starvation is detectable and would be cause for voided warranties. Please make sure you plan out your fuel system build with proper low pressure upgrades when necessary.
