Spool Performance Stage 2 Low Pressure Fuel Pump [FXX N55] - SP-BMFXXN-FPS2

Spool Performance is proud to introduce the Stage 2 Low Pressure Fuel Pump (LPFP) upgrade for the BMW FXX N55 platform. This plug-and-play solution addresses one of the most common fuel system bottlenecks when chasing high horsepower on the N55—especially on ethanol-heavy fuel blends like E85.

With direct injection systems now supported by upgraded high-pressure fuel pumps (HPFPs), the low-pressure fuel pump becomes the next critical limitation. The Stage 2 LPFP helps overcome this by offering increased fuel delivery, reliability, and support for high-performance builds.

Why You Need It:

• Up to 30% More Flow vs. OEM Pump:
  The upgraded pump is engineered to flow 30% more fuel than the factory LPFP, translating to support for up to ~600hp worth of low-pressure fueling, no matter the fuel type.

• E85-Compatible:
  Whether you’re running full E85 or blending, this pump handles ethanol content with ease.

• Plug-and-Play Installation:
  This is a drop-in replacement—no need to modify the pump assembly or return a core. Everything is preassembled for convenience.

• Supports Upgraded HPFPs:
  Designed to pair perfectly with Spool FX-series HPFPs (like FX-150, FX-170, and FX-200), ensuring a fully balanced and reliable fuel system from tank to injector.

Fitment:

This kit fits the BMW FXX N55 platform, including:

• F22 M235i / 235i
• F30 335i / 335i xDrive
• F32 435i / 435i xDrive
• Other N55-powered F-series chassis models

If you're unsure whether your vehicle fits, feel free to ask—we’ll confirm compatibility with the manufacturer.

Important Disclaimer:

Primary Pump Connector Melting Notice
Damage to the primary pump connector caused by overloading the EKP module (typically from aggressive tuning or excessive power demands) is not covered under warranty. This is not a manufacturing defect, but rather the result of pushing the OEM controller beyond its intended limits.

We strongly advise against overtaxing the EKP with high-demand tunes unless you are supplementing with a secondary pump or upgraded EKP control strategies.

What You Get:

• Pre-assembled Stage 2 LPFP assembly
• OEM-style drop-in fitment
• Fully ethanol-compatible
• No core returns or additional assembly needed
