Unlock reliable fueling for tuned BMW N54 and N55 builds with this DW400 Stage 2+ bucketless low pressure fuel pump upgrade. Designed as a direct in-tank, plug-and-play replacement for the factory LPFP, it is E85 compatible and built to support higher demand from performance maps and ethanol blends. This Stage 2+ configuration delivers up to 50% more flow than a standard Stage 2 upgrade and up to 200% more than the stock pump for increased headroom where it matters.

Important notes:
- This bucketless kit uses a basic filter assembly. Running with very low fuel can cause starvation. For hard straight-line acceleration with less than 1/8 tank, or for circuit use with less than half a tank during long right-hand corners, you may experience fuel starvation. For those scenarios, consider a standard bucketed pump solution.
- High-flow pumps draw more current. A weak EKP (LPFP control module) can overheat and shut down. Ensure your EKP is in good health before installation.
