Description
The BMW “TU” High Pressure Fuel Pump – Bosch 0261520520 is a direct OE replacement and performance upgrade for BMW B48 and B58 engines. Engineered by Bosch, this HDP-6 pump delivers significantly higher fuel flow than the stock HDP-5-EVO, making it the preferred solution for tuned or modified applications.
Pump Specifications:
- HDP-5-EVO: 0.954 cc/rev, up to 250 bar
- HDP-6: 1.178 cc/rev, up to 350 bar
This upgrade ensures increased fueling performance, improved engine efficiency, and supports higher power output on tuned BMW vehicles.
Installation Notes:
- For Gen 1 B58/B48 engines, the connector housing for the fuel quantity control valve may need to be rotated.
- No additional harness is required, though an extension harness can be used if preferred.
- ECU tuning is required to maximize performance gains.
Direct Injection High Pressure Fuel Pump Overview:
High-pressure fuel pumps (HPFP) are essential for modern direct injection (GDI) engines, boosting fuel pressure to over 2,000 psi to allow precise fuel delivery directly into the combustion chamber. This improves fuel atomization, efficiency, and power output. HPFPs are camshaft-driven and work alongside low-pressure fuel pumps. Over time, wear, contamination, or failure can cause drivability issues, including hard starting, misfires, loss of power, or fuel leaks.
