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.

These kits are designed to be installed inline with your stock low-pressure fuel pump (LPFP).  They provide approximately 50% more flow when combined with your stock pump.

Kit includes the following:

  • SAE J30R10 E85 compatible fuel line
  • 14ga fuel resistant wiring harness
  • Quick connect female bullet connectors (2)
  • Vent tube replacement clip
  • Nylon cable ties (10)
  • Stainless steel lock nuts (2)
  • 10ga/14ga step-down butt splices w/E85 compatible heat-shrink tubing (2)
  • Pushlock pump retention fittings (2)
  • 14ga butt connectors w/heat-shrink tubing for pump removal to return to stock if/when desired (2)

    *Note:  Walbro does not warranty this pump for E85 use.  If your application requires an E85 certified pump you may want to consider selecting a Stage 2 fuel kit.

    ** IMPORTANT:  Do NOT attempt to run this kit inline with a Stage 2 kit.  The Stage 2 kit is a higher flowing kit and this will not only restrict the flow of the stage 2 kit, it will result in failures.

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 E-Chassis 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 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. Select WMI Ethanol Setup option 1 to enable pin location 15/16 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.
