Dorch B58 Gen2 DS3 HPFP

After significant research and development, we are proud to introduce the single largest flowing high-pressure fuel pump on the market: the DS3 (Dorch Stage 3). This is our largest diameter piston and best flowing pump to date, allowing for very large power numbers with a HPFP upgrade alone.

The DS3 is the same reliable, OEM drop-in solution our customers have come to expect, but provides 20% more fuel capacity than our DS25 model.

As with our other kits, installation requires no cutting, bending, or crimping of lines. An OEM quality high-pressure fuel line is included, and the entire kit is a direct drop-in. The DME fully controls the pump in the exact same manner as the factory system.

By combining the DS3 pump with Dorch Performance injectors and one of our camshaft solutions, you can achieve unprecedented four-digit direct injection power figures.

Please Note

While the factory S58 injectors are a cost-effective pairing for the DS25 pump, the DS3 requires even larger flowing injectors to utilize its full potential.

Software Requirements

This pump requires software changes to operate.

• If you are on Bootmod3 or MHD, please select the Dorch pump upgrade during the flash (support coming soon).
• Otherwise, please email your .BIN file to tuning@dorchengineering.com for WinOLS changes.

Why Choose Dorch?

Plug and Play

This is the only true plug-and-play OEM-fitment solution on the market. The kit includes a high-pressure line designed for 350 bar operating pressure, allowing the HPFP to easily connect to the fuel rail without bending or potentially damaging the original line.

Lifetime Warranty

We can offer a lifetime warranty because our pumps are extremely reliable. However, should any issues arise, we are here to help resolve them.

Dorch is known for exceptional 24/7 customer support. You will have access to the expertise of professional engineers, technicians, and software tuners quickly via email.
