Direct Fit high Pressure Fuel Pump Upgrade for your Fiesta ST, Ecoboost Mustang, Raptor and Focus ST!

CUSTOM TUNING IS REQUIRED, YOU CANNOT RUN THIS ON A STOCK TUNE. PLEASE MAKE SURE YOU HAVE A TUNE PURCHASED WITH US. 


HPFP35 - 35% more flow at 2900psi
EVO - 12% more flow over the HPFP35 at 2900psi. 

Fiesta ST - Please see our full R&D post HERE 

Focus RS (EVO Pump Only) - EVO Pump w/ Injectors required for full E85 on stock turbo, will support up to 550whp on E85. (Built engine and turbo upgrade obviously needed to hit this power number)

Raptor (EVO Pump Only) - So far with testing we have reached 500whp on stock turbos with E50 and just the EVO fuel pump. This was on 37" tires, with 35" stock tires we would see about another 30-40whp. HPFP35 not available. 

Ecoboost Mustang - HPFP35 or EVO Pump w/ Injectors required for full E85 on stock turbo, will support up to 550whp on E85. (Built engine and turbo upgrade obviously needed to hit this power number)

Focus ST - HPFP35 or EVO Pump w/ Injectors required for full E85 on stock turbo, will support up to 450whp on E85. (Built engine and turbo upgrade obviously needed to hit this power number)

If you choose to run a race fuel with a stoich point of 14.08-14.7 you will be able to make well over 600whp with the pump and injector combo. E85 is more demanding on the fuel system and has a stoich point of 9.85 hence why it needs 30% more fuel demand than pump gas or race fuel with a stoich point of 14.08-14.7. 

Injector info:

Fiesta ST 50% Injectors - HPFP35 or EVO pump is required to run straight E85 with these injectors. Cannot use the stock pump or a Nostrum pump. XDI pump/50% injector combo will support up to 375whp on E85 with the stock IN TANK PUMP. With our future lowside/in tank pump upgrade you'll be able to run E85 up to 450whp until you are out of injector. This combination can support E50 up to 500whp. PRICE INCLUDES DOUBLE SEAL UPGRADE! EVO Pump is recommended for customers looking to make over 375whp.  

Fiesta ST 30% Injectors - Injectors only can support 330whp on E30. Injectors and XDI HPFP35/EVO pump can support E50 up to 420whp. PRICE INCLUDES DOUBLE SEAL UPGRADE!
