Show original supplier description

The Fuel-It! B58 BMW HPFP Upgrade is designed to replace the factory high-pressure fuel pump in Gen 1 B58 powered BMW vehicles. This upgrade is available in two stages: Stage 1, which offers 30% more fuel flow than stock, and Stage 2, capable of supporting 60% more flow. The Stage 2 pump is built around the GM LT4 pump part number 12711668, and the Stage 1 is built around the GM LT1 pump part number 12669519. The basic kit includes everything needed for installation: an upgraded High-Pressure Fuel Pump (HPFP), a billet adapter plate, a billet center alignment tool, a low-pressure line with triple-lined crimped fittings (PTFE/SS/Nylon Braided), and a custom harness with hardware. A plug-and-play installation is intended, though a flash tune is required to enable the "Stage1" or "Stage2" functionality. For those who prefer to source their own HPFP, Fuel-It! also offers an "Install Kit Only" option, which includes the harness, adapter plate, install jig, and lines. This kit is specifically for Gen 1 B58 Powered BMWs. The compatible vehicle list includes various BMW 1, 2, 3, 4, 5, 6, 7 Series, and X Series models from approximately 2014-2020, depending on the specific model and engine variant. It is crucial to verify fitment based on the vehicle's build date and specific platform designation (e.g., M140i, M240i, 340i, 440i, X3 M40i, etc.).
