Unlock more low-side fueling on your BMW E series with this Stage 3 bucketless LPFP upgrade kit for N54 and N55 engines.

Supplied by Nforcd and built around proven Walbro hardware, it is a straightforward, plug-and-play upgrade for serious builds.

Important note on fuel level: this bucketless kit uses a basic filter assembly. Running the car with very low fuel can lead to fuel starvation. For hard straight-line acceleration with less than 1/8 tank, we recommend using a standard Stage 2, Stage 3 or Stage 4 pump assembly. For circuit use, starvation may occur when running less than half a tank during long, high-G right-hand turns. For those applications, consider one of the standard pump assemblies.
