What is the FX-150?

The FX-150 is an upgraded high-pressure fuel pump. The pump features a bigger bore size than stock that translates into roughly 50% 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.


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-150 adds 50% 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?

Our FX-150 kit for the M177 includes

2 x FX-150 upgraded high-pressure fuel pumps

1 x Ethanol Content Monitor with mobile apps

1 x Bosch spec 10-micron high flow Fuel Filter

Upgraded Fuel lines and all necessary install hardware


***Low Pressure Fuel Pump Upgrade Requirement

Due to the higher flow requirement of the FX-180 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-180 HPFP would be excluded from any warranty coverage. Please reach out to us at customer_service@spoolperformance.us if you have any questions regarding this.


Spool 10-micron filter unit

Our 10-micron filter unit boasts the best filtration available on the M177 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 for the M177 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. The ECA module also has a 0-5V filtered output for flex-fuel implementation on the M177 platform if needed. 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.
