Spool FX-200 High-Pressure Fuel Pump – BMW B58 Gen 1

Spool FX-200 High-Pressure Fuel Pump for BMW B58 Gen 1 is a Stage 2 HPFP upgrade designed to substantially increase direct-injection fuel capacity over the factory pump.

• Supplier states approximately double stock pump flow
• E85 compatible
• Plug-and-play pump architecture with no cutting or splicing required
• Supports higher ethanol content and larger-turbo combinations when correctly calibrated

Selectable options: wireless ethanol analyzer, 10-micron filter and stainless-steel high-pressure fuel line.

Important: calibration changes must be applied before starting the engine with the upgraded pump installed. Adequate low-pressure fuel delivery is essential.

Dispatch: Special order — allow 2–3 weeks.

Fuel-system selection and installation

Fuel-system parts must be selected around the complete combination of engine generation, fuel type, target output, existing pump and injector configuration, and the calibration strategy. A component appearing for an engine family does not mean it replaces every factory or upgraded fuel-system arrangement used on that engine.

Professional installation and calibration are recommended where the product changes fuel pressure, pump control, injector flow, ethanol-content input or port-injection operation. Confirm wiring, plumbing, electrical load, controller requirements and compatible supporting hardware before ordering.

Before ordering

Select your exact BMW through MLAB My Garage and review the product options, included parts and installation requirements. Where a vehicle has been modified from its original engine, transmission or fuel-system specification, contact MLAB with the VIN and current hardware list so the combination can be checked before supply.

MLAB support

MLAB by Boost and Tune can assist with product selection, workshop installation and dyno calibration for supported BMW applications in Melbourne. Product availability and lead time should be confirmed when ordering supplier-built or special-order components.
