Spool FX-180 upgraded high pressure pump kit Mercedes AMG C43, GLC43 M276
 
What is the FX-180?
 
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.
 
Why do you need it?
The stock HPFP on the M276 Motors is severely limited in capacity when trying to tune and raise the output of the motor. The FX-180 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?
Our FX-180 kit for the M276 includes
1 x FX-180 upgraded high-pressure fuel pumps
1 x Ethanol Content Monitor with mobile apps
1 x Bosch spec 10-micron high flow Fuel Filter

***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.
 
Our 10-micron filter unit boasts the best filtration available on the M276 market without any noticeable pressure drop in the low side fuel system. 
 
Spool Ethanol Content Monitor
The spool ECA kit for the M276 features a digital readout of in-tank ethanol content and fuel temperature.
 
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.
