This low-pressure fuel sensor is commonly a cause of an "Increased Emissions" warning on the idrive and for check engine (SES) lights on BMW's with the N54 6 cylinder turbo engine or the S65 V8 engine in the M3. It will also fit a limited number of cars with the N55 engine. This sensor can be traced to a number of drivability issues, including cold start running problems, misfires, stumbling, hesitations, and overall rough running. You will likely have a code for the misfires, rich condition, or for the sensor itself. In some cases, the combination of codes can bring about a limp mode. Replacing this sensor is an easy and inexpensive first step if you're having any of these issues. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

This is a complete plug and play solution to replace your stock Low-Pressure Fuel Pump (LPFP) with a new E85 certified bucketless assembly.

This solution provides up to 25% more flow than our standard Stage 2 LPFP upgrade and up to 150% more flow than the stock pump.

This pump will support up to 550whp running 85% ethanol and 600whp running 50% ethanol.

The Stage 2 bucketless kit includes the following:

- A custom anodized billet fitting for the pump output and stock fuel line connection.
- Our custom billet aluminum anodized bracket for the pump and float assembly
- Two cotter pins to secure your float assembly
- A new E85 compatible Walbro 450 pump
- Spare vent tube clip
- A new Walbro filter

If you still need more flow, the Stage 3 upgrade is also available and can be added to your Stage 2 bucketless pump.

The Stage 3 upgrade kit includes:

- A complete plug and play solution by simply adding the secondary module
- Our custom billet aluminum fitting to run both pumps in parallel
- A new E85 compatible Walbro 450 pump
- Wiring harness for the secondary pump
- Spare vent tube clip
- A new Walbro filter

Recommended accessories:
- Lock Ring Removal Tool
- Hobb's switch
NOTE: These kits include a basic filter assembly. When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump. In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns. Again for those applications we'd recommend one of our standard pump applications.

This is a complete Low Pressure Fuel Pump (LPFP) upgrade that replaces your weak stock LPFP assembly with a high-flow E85-certified one. Standard Kit Includes: A brand new OEM LPFP bucket that is upgraded with a new Walbro 450 or 525 pump and filter. A new E85 compatible Walbro 450 pump (F90000274) that flows 50% more fuel than stock Optional A new E85 compatible Walbro 525 pump (F90000285) that flows 65% more fuel than stock NOTE: Owners with I-Drive may get a Fuel pump warning on the screen that says "Continued driving is possible. Have the system checked by your BMW center as soon as possible." As long as the car is running fine and does not exhibit any other symptoms, there is not an issue with the pump and this can be ignored. If you have any questions about this please feel free to contact us. Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced. If this is a concern for you check out our Stage 3 fuel pump upgrade kits that retain the stock LPFP and add a secondary pump.

This is a complete plug and play kit to install a Bluetooth ethanol sensor in your E-Series BMW. (Check compatibility for your platform below) This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgrade -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer to monitor your ethanol content. This kit features a 0-5 volt analog output that integrates with the JB4, analog gauge, or any other ECU or tuner that supports 0-5 volt input. All of these kits utilize a custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed. 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. *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. *For the BMW N54 E-series JB4 platform connect the white wire to position #15 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *For the BMW N55 E-series JB4 platform connect the white wire to position #16 on the JB4 25 pin harness.
