Clear BMW chassis

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.

We are proud to bring out this truly awesome product that makes getting the required Flex Fuel hardware on your BMW and A9X Supra 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
  • All connecting points sealed with fuel safe Viton o-rings
  • Flex Fuel Sensor Adapter housing provides additional 1/8 NPT ports for optional Fuel Pressure sensor addition to vehicles without a factory one for bootmod3 CustomROM v2 support
  • CANBUS Enabled Ethanol Content Analyzer (ECA) that integrates with bootmod3 CustomROM for complete and seamless conversion of your BMW to FlexFuel for bootmod3 Flex Fuel enabled OTS MultiMaps and custom tunes with your bootmod3 tuner of choice
  • Power/CANBus 4-wire plug and play harness
    • 100% Fully Plug and Play harness to the BMW Fuel Controller connectors (EKP3) on S55, N55 vehicles
    • 100% Fully Plug and Play harness on the BMW Body Domain Controller (BDC/FEM) connector on Gen1 F-series B48/B58
  • Continental Flex Fuel sensor 3-wire harness
  • Custom Aluminum-6061 CANBus Enclosure for the bootmod3 ECA board

A Must For Cars With Upgraded LPFPs The full plug-and-play EKPM3 cooler kit is designed specifically for F80, F82, F83, and F87 (Comp) 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 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.

If you are running E85 or ethanol mixes in your BMW, you need this kit! This is a complete plug and play kit to install a Bluetooth ethanol sensor in your S55 BMW. This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgraded -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer to monitor your ethanol content. Includes both Bluetooth App & 5v analog output for JB4 or flash tuning. For your fuel line upgrade, choose the option that supports your current configuration. HPFP to the fuel tank: (Stock) This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor. Port Injection to the fuel tank: If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel. Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup. Non-Fuel-It! port injection to fuel tank: Choose this option if you are running a port injection kit that we did not manufacture or sell. This kit includes a longer 18" feedline from the Y to the port injection rail. You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail. All of these kits utilize the BMS custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed. *For the BMW F-series JB4 platform connect the white wire to position #16 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *These kits are available for off-road use only *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
