Spool Stage 3 DIY LPFP Kit – BMW B58 Gen 2
Spool Stage 3 DIY LPFP Kit for BMW B58 Gen 2 is a drop-in secondary-pump upgrade for G-chassis BMW B58 applications, with selectable Walbro pump and activation-harness configurations.
- Walbro 450 or Walbro 525 secondary-pump choice
- Three supplier-listed activation harness choices for Hobbs-switch or ReFlex-controlled builds
- Three-piece bracket system designed to secure the pump without cutting the factory fuel bucket
- Supplied hose and fittings tee into the factory fuel line
- Walbro 450 is the supplier-recommended choice for most applications
- Walbro 525 is intended for higher fuel-flow requirements; Spool recommends PWM control because of its higher current draw
Fitment: Spool states the kit supports G-chassis BMW B58 vehicles. Vehicle year, model or VIN should be supplied when ordering because BMW uses multiple fuel-tank bracket designs.
Optional items: Spool lists a pre-drilled OEM top hat and Holley Hydramat separately; they are not automatic variants in this M Lab listing.
Dispatch: Special order — allow 2–3 weeks.
