Product Description

We currently offer four options to upgrade the fuel feed lines on your and N55 equipped 135i, 235i, 335i, F-series BMW.  All fuel lines upgrades are 3/8" (AN6) and E85 compatible.  In addition we utilize our own custom fittings made specifically for your BMW so that you can maintain the stock connections at the HPFP, the tank, and the ethanol sensor should you choose to install one.

  • HPFP to the Tank:
    • This upgrade replaces both stock fuel lines with one upgraded countinous fuel line from the fuel tank to the HPFP.
  • HPFP to the Tank with Ethanol Sensor:
    • For those that want to run ethanol, we also offer this upgrade with an integrated ethanol sensor.
      • Note: An ethanol analyzer must be used in conjuction with the ethanol sensor to read your ethanol content.
      • There are two options to read your ethanol content when using our ethanol analyzers:
        • JB4 integrated (0-5 Volt) 
        • Bluetooth (Iphone or Android app must be purchased to use this feature)
  • Port Injection to the Tank:
    • If you are running port injection, this upgrade replaces the stock fuel lines from the tank to the engine bay and then utilizes a Y adapter to supply the HPFP and PI with fuel.  This removes those tee's and extra fittings for a cleaner high flow setup.
  • Port Injection to the Tank with Ethanol Sensor:
    • For those that want to run ethanol, we also offer this upgrade with an integrated ethanol sensor.
      • Note: An ethanol analyzer must be used in conjuction with the ethanol sensor to read your ethanol content.
      • There are two options to read your ethanol content when using our ethanol analyzers:
        • JB4 integrated (0-5 Volt) 
        • Bluetooth (Iphone or Android app must be purchased to use this feature)

*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.
