High Pressure Fuel Pump

The Bosch High Pressure Fuel Pump (HPFP), part number 13518631642, is engineered as a direct replacement or performance upgrade for various BMW, Mini, and Toyota Supra models equipped with B46D, B48, B58, B58TU, or S58 engines. This external, 12-volt fuel pump is a critical component in direct injection systems, boosting fuel pressure to levels often exceeding 2,000 psi for efficient combustion. This genuine Bosch HDP6 pump is designed to maintain or enhance your engine's peak performance. A failing high-pressure fuel pump can commonly lead to Check Engine Lights and the vehicle entering limp mode. This unit is designed as a 100% direct bolt-on, with some sources indicating a quick swap time of approximately 15 minutes. This high-pressure fuel pump is compatible with a range of vehicles including the BMW 1 Series F40, 2 Series F44 Gran Coupé, 3 Series (e.g., 330i xDrive, 340i), 4 Series (e.g., 430i, 440i), 7 Series (e.g., 740i), X5, and X6, as well as the Toyota Supra. It also serves as an upgrade for the B46/B48/B58 engine variants, potentially supporting up to around 600HP on gasoline when used as an upgrade.
