Please ensure your correct model is selected

BMW fuel system kits provide a comprehensive solution for maintaining and upgrading the fuel delivery system, ensuring optimal engine performance and efficiency. Over time, fuel pumps, injectors, filters, and pressure regulators can wear out, leading to poor fuel economy, hard starts, misfires, and engine hesitation. Common problems include clogged fuel injectors, failing fuel pumps, and fuel pressure inconsistencies, which can result in rough idling and reduced power. Upgrading or replacing worn components with a complete BMW fuel system kit restores proper fuel flow, enhances throttle response, and improves overall drivability. Our selection of OEM and high-performance BMW fuel system kits includes everything needed for a reliable fuel system refresh, ensuring a precise fit and long-lasting durability for a wide range of BMW models.

  • Versatile Measurement: Capable of measuring fuel pressure, boost, coolant, oil, and other fluids.
  • Easy Integration: 2-Pin DTM connector provides a direct plug-and-play connection.
  • Comprehensive Monitoring: Supports integration of up to two sensors per ReFlex+ unit.
  • High-Performance Design: Designed to handle high pressures and deliver accurate readings.

For optimal installation, consider using the 3/8 Female to 3/8 Male SAE Quick Disconnect Adapter with a 1/8" NPT port on an ethanol sensor or the 5/16 Female to 5/16 Male SAE Quick Disconnect Adapter with a 1/8" NPT port on a factory fuel line. Please note that the ethanol sensor is not included.

The full plug-and-play EKPM3 cooler kit is designed specifically for F22/F30/F31/F34 BMWs using an EKPM3 fuel pump control module. This is recommended for anyone using a low-pressure fuel pump that is larger than the OEM fuel pump. We designed this kit with the help of Island Racewerks. The cooler housing is designed to fit over the EKP module just like the OEM housing and fits with plenty of room in the stock EKP location. The housing is 3D printed using durable PLA+. The full kit is printed and assembled in the U.S.A. by Arc Terminator LLC. Full Kit Contents: 1x EKPM3 Cooler Housing With 5015 Fan or 60mm Noctua Fan (depending on choice) 1x 14x14x6mm Heatsink With Thermal Tape 1x 14x9x5mm Heatsink With Thermal Tape 1x 9x9x5mm Heatsink With Thermal Tape (EKPM3 Kit) 4x 4" Zip Ties 1x Alcohol Wipe 1x 2 Amp Mini Blade Fuse Why this kit exists: The EKPM3 and EKPM2 have been shown to overheat and cause vehicle shutdown issues when larger fuel pumps that draw more current than OEM are used. This shutdown comes from critical components on the EKPM3 and EKPM2 overheating when larger current draws are coming from the fuel pump. The PNP kit comes with heatsinks for the most heat-sensitive and heat-producing components in the EKPM3 / EKPM2 to further increase cooling effectiveness. When paired with a potent 5015 blower fan that directs a large amount of airflow through the cooler housing, the EKPM3 / EKPM2 stays significantly cooler, which prolongs the life of the module. We also recommend anyone using a larger fuel pump than OEM to properly code their EKP module with Pro-Tool's built-in "Voltage Fix" feature.

We are proud to bring out this truly awesome product that makes getting the required Flex Fuel hardware on your BMW with incredible ease and minimal effort, in your own driveway.


Our kit is entirely plug-and-play with the factory vehicle harness. No cutting or splicing of OEM wiring/connectors. It installs in minutes and can be removed without a trace on the car!


Our team used SolidWorks to design a Flow Optimized Flex Fuel Sensor Adapter (FFSA) to ensure fuel flow is unobstructed and with no added pressure drop at full fuel pump flow from the fuel tank to your motor when our kit is installed. This is important when pushing the factory fuel system with all the power Ethanol can provide over petrol!


Flex fuel sensor housing is designed to neatly install into the factory BMW fuel hat location.


Flex Fuel Sensor Adapter also contains two 1/8 NPT ports that allow installation of an auxiliary Fuel Pressure sensor for vehicles that don’t come with an OEM one from the factory for future use. Depending on fitment, either port can be used.


Install the bootmod3 Flex Fuel Plug and Play Kit and flash your flex fuel enabled bootmod3 OTS MultiMap or Custom Map in minutes and you’re off to the races never worrying about alcohol/petrol blend % in your fuel tank. It does not get better or easier than this!


bootmod3 FlexFuel Plug and Play Kit:


Minutes to install at home as opposed to hours at a shop with car up on lift fabricating/cutting into factory fuel lines and splicing/cutting/pinning into OEM electrical

4+ hours in time/cost savings to get going on Flex Fuel as compared to most other kits that require making custom fuel lines, fittings, and custom wiring! 

Fully reversible/removable and back to stock without a trace in minutes

Custom 3-piece Aluminum-6061 Flex Fuel sensor adapter with built-in sensor bypass to allow for obstruction-free fuel flow made to fit in the vehicle factory fuel hat area below the rear seat
