BMW F8X S55 Flex Fuel Kit | Fuel-It! from Turner Motorsport is essential for those running E85 or ethanol blends in their BMW. This comprehensive kit offers a plug-and-play solution for installing a Bluetooth ethanol sensor in your S55-powered vehicle.
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:
*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.
This is a complete Low-Pressure Fuel Pump (LPFP) upgrade that replaces your stock LPFP assembly with a new E85 certified one. The new Walbro 450 pump provides approximately 100% more flow than stock and this assembly can be purchased one of three ways to meet your needs.
Both options include the following:
To be eligible for a core return, the bucket must be completely stock and undamaged. (Pump itself does not have to be functioning)
+ International customers: Due to different emissions requirements, the top portion of your fuel bucket (top hat) is different and doesn't have a large vent tube connection. For this reason, we are no longer sending the top hat to international customers as this often causes confusion. Those customers will simply re-use their current top hat when installing their Stage 2 pump.
- All Stage 2 assemblies are stock buckets that have been rebuilt and may show signs of being disassembled and rebuilt. They are all flow tested and verified before being shipped.

Are you running more E85 or making more power on pump gas than your HPFP (High-Pressure Fuel Pump) can support?
Fuel-it has developed a port injection kit for your S55 that will provide you with the additional fueling capacity that you need to be able to run up to 100% E85 on stock or upgraded turbos.
What is port injection?
Port injection is a kit that is installed between your intake manifold and the cylinder head that runs off the low-pressure supply to provide you with more fueling than your stock system is capable of. It's a relatively easy system to install and does not require any permanent modification to your car.
Port injection kits are offered in five different packages to meet your needs:
Base port injection kit: (included in Bronze, Silver or Platinum Kits)
Bronze kit includes:
Silver kit includes:
Platinum kit includes:
*These kits are available for off-road use only
*All port injection kits are built to order.
*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.
