Dorch Engineering DS25 High Pressure Fuel Pump HPFP - BMW F20 M140i | F22 M240i| F30 340i | F32 440i (B58)

NOTE: If you already have an ethanol sensor in your car, simply choose the correct chassis fitment and type “ECA HOSES” in the order notes.

From the creators of the world’s first B58 direct-injection fueling upgrades, comes our next generation of pumps. Our widely successful “Dorch Stage 2” (DS2) has been replaced with our latest and greatest creation; the DS25! This new pump is our “Stage 2.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the packaging to provide exact OEM hose routing for ZERO interference when changing out coil packs or spark plugs. There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like factory. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.

What does this mean? It means the most reliable and highest flowing B58 pump on the market just got even MORE reliable and even MORE flow! The DS25 is also designed to run efficiently all the way up to 250 bar in order to maximize the flow potential of upgraded DI injectors:

Software changes are required to run this pump. If using Bootmod3, MHD, or MG Flasher, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software changes. This change is free of charge for all of our customers.
