Labyrinth Automotive Gen 1 B58 HPFP Kit

The factory high-pressure fuel pump is one of the first major bottlenecks encountered when pushing the Gen 1 B58 beyond stock power levels. As boost, airflow, and ethanol content increase, fuel demand quickly exceeds what the factory fuel system was designed to support.

The Labyrinth Automotive Gen 1 B58 HPFP Kit was engineered to eliminate that limitation and provide the fueling headroom required for modern high-performance B58 builds. Featuring a 1.558 cc/rev displacement, this system delivers a substantial increase in fuel volume over the factory pump, helping support the demands of increased boost, ethanol blends, and larger turbocharger combinations. Whether you’re maximizing a stock turbo setup, running ethanol blends, or preparing for larger turbocharger upgrades, this kit delivers the fuel volume needed to support your goals while maintaining excellent drivability and OEM-like operation.

Tested at 880+ WHP on direct injection only, the Labyrinth HPFP Kit has proven itself capable of supporting some of the most demanding Gen 1 B58 combinations while retaining the simplicity and reliability enthusiasts expect.

Unlike pieced-together solutions, every Labyrinth HPFP Kit includes all of the components required for installation. Each kit comes complete with our custom-machined pump spacer, premium fuel hose assembly, high-quality quick-connect fittings, electrical adapter, and all necessary hardware.
