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 Low Pressure Fuel Pump (LPFP) upgrade for those customers that need the additional capacity to meet their power goals on pump gas, race gas, or E85. It utilizes a stock pump for the primary pump so that your EKP operates as intended by the factory eliminating potential errors for current draw and the secondary pump then runs under high boost only. For power levels up to 700whp we'd recommend using the standard 450 pump and beyond 700whp we'd recommend upgrading to the 525 pump. F-Series B58 (Gen 1) Stage 3 assemblies include: New stock LPFP Secondary pump assembly Secondary wiring harness Walbro filter Walbro 450 pump (F90000274) Compatible with the following vehicle production dates: 1' F20 LCI (05/2014 — 06/2019) 1' F21 LCI (05/2014 — 06/2019) 2' F22 (06/2014 — 06/2017) 2' F22 LCI (09/2016 — 12/2019) 2' F23 (06/2014 — 06/2017) 2' F23 LCI (09/2016 — 12/2019) 3' F30 LCI (09/2014 — 10/2018) 3' F31 LCI (09/2014 — 06/2019) 3' F34 GT LCI (09/2015 — 12/2019) 4' F32 (04/2015 — 02/2017) 4' F32 LCI (05/2016 — 12/2019) 4' F33 (03/2015 — 02/2017) 4' F33 LCI (05/2016 — 12/2019) 4' F36 Gran Coupé (05/2014 — 03/2017) 4' F36 Gran Coupé LCI (05/2016 — 12/2019) *Note: Secondary pump can NOT run full time. We recommend using a Hobb's switch to trigger the secondary under high boost. See the installation process here: https://www.youtube.com/watch?v=YoPf0F7PBt8

As these cars get older we're seeing more issues with the stock components and more demand for cost-conscious fueling solutions. The new Fuel-It 650HP line of fuel system upgrades are designed with those needs in mind while maintaining a budget. They make the most of the stock components to maintain stock reliability and drive-ability but when the boost gets cranked up, the Fuel-it 650HP components kick in to support the additional fueling needs of your high horsepower car. With the Fuel-It 650HP lineup, you can upgrade your components all at one time or upgrade them as time and budget allows. If upgrading one component at a time, we'd recommend starting with the LPFP first as that is the heart of your fuel system, without a good Low Pressure Fuel pump (LPFP) you can't supply the fuel needed to any of your other components. Your secondary pump can NOT run full time, it must only be run under boost only. Running it full time will place additional strain on the stock system, will lead to high fuel temps, and pump or component failure. To turn the secondary pump on under boost we recommend running the included 4psi Hobb's switch. Included with all S65 LPFP upgrades: Walbro 450 pump (F90000274) Black Anodized Custom fitting Pump brackets 9/64" terminals and associated hardware Fuel line Replacement PITA clip Wiring harness

As many of you know the BMW motors can be very picky about how much ethanol you run to achieve peak performance but not run lean. Consequently, BMS have put together a kit enabling you to easily install an ethanol sensor with no permanent modifications needed. You will simply remove your low pressure fuel line in the engine bay and plug in our kit. It's a complete plug and play solution that utilizes our Bluetooth app to monitor your ethanol content. When you are ready to return to stock, you will simply remove the kit and re-install the stock fuel line. The complete kit includes the following: Genuine Continental ethanol sensor Fuel-It! Bluetooth Universal Analyzer Two stainless steel braided fuel lines with black nylon sheathing to protect your other engine bay components Proprietary custom billet fittings for plug and play OEM integration One wiring harness with Posi-tap connector Bluetooth Model Supports stand-alone Bluetooth operation with the Fuel-It! app *For the JB4 platform connect the white wire to position #4 on the JB4 25 pin harness. Select WMI Ethanol Setup option 0 to enable pin location 2/3/4 flex fuel input. *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.
