Dorch Engineering B58 Gen1 DS25 HPFP Upgrade - F Chassis

Product Details

 For the Gen 1 B58 engine found in the F-chassis 1–4 Series, the factory high-pressure fuel pump simply cannot keep pace with aggressive tuning, upgraded turbos, or high-ethanol blends. The DS25 is built to endure the thermal stress and high-rpm demands of hard driving. This kit provides a massive volumetric flow increase over stock, ensuring your rail pressure remains perfectly stable at high load. 
 

Features & Fitment:

• Fits Gen 1 B58 engines (F22 240i, F30 340i, F32 440i, etc.)

• Engineered to handle aggressive ethanol blends (E85 capable)

• Complete kit includes all necessary hardware and plumbing for a seamless install

• Absolute stability at high rail pressures for maximum engine safety
