Description
Expand your Ford F-150 Raptor's fueling and tuning capabilities with the COBB Tuning CAN Flex Fuel Upgrade Kit, designed for the 2017–2020 Ford F-150 Raptor 3.5L EcoBoost. This performance upgrade measures the ethanol content of the fuel in your tank and communicates that information to the engine control unit (ECU), allowing compatible COBB Accessport flex-fuel calibrations to adjust engine operation according to the fuel blend.
The system uses a dedicated ethanol sensor, COBB CAN Gateway module, and vehicle-specific wiring harness to integrate fuel composition data into the vehicle's CAN communication network. This allows supported ECU calibrations to account for changes in ethanol content, helping enthusiasts take advantage of compatible gasoline and ethanol-blended fuel setups.
CAN Gateway Integration
The included COBB CAN Gateway provides a connection between aftermarket sensor data and the vehicle's CAN system. Housed in a billet aluminum enclosure with a precision-manufactured circuit board, the gateway communicates ethanol-content information to the ECU for use with supported COBB Off-The-Shelf (OTS) maps or custom tuning.
The vehicle-specific wiring harness is designed for integration with the 2017–2020 Ford F-150 Raptor. The kit also includes an ethanol sensor, mounting bracket, fuel lines with quick-connect fittings, and the associated wiring harness.
Designed for Performance Builds
The COBB CAN Flex Fuel Upgrade is a supporting modification for Raptor owners seeking greater flexibility in fuel selection and ECU calibration. When paired with a compatible Accessport and appropriate flex-fuel tune, the system can help optimize engine operation for the measured fuel composition.
Manufactured by COBB Tuning, this kit is designed for enthusiasts building a performance-focused 3.5L EcoBoost Raptor. Additional fueling hardware may be necessary depending on ethanol concentration, engine modifications, and the selected calibration.

Fitment
2017–2020 Ford F-150 Raptor 3.5L EcoBoost — USDM
Important Fitment Note: COBB identifies the kit for 2017–2020 US-market Ford F-150 Raptor models. Do not assume compatibility with standard F-150 trims, other EcoBoost engines, non-US-market vehicles, or later Raptor generations without manufacturer confirmation.
SuperCab Compatibility: COBB notes that the standard kit's fuel line is not directly compatible with SuperCab trucks. Contact COBB Tuning for the appropriate fuel-line solution before ordering for a SuperCab configuration.
Installation & Compatibility Notes
-
Requires a compatible COBB Accessport and an appropriate flex-fuel calibration to use the measured ethanol content for engine tuning.
-
Confirm that your Accessport, ECU software, and selected calibration support CAN Flex Fuel functionality.
-
Installation involves the ethanol sensor, fuel lines, wiring harness, and CAN Gateway module.
-
The CAN integration harness may require access behind the radio or cockpit control unit.
-
Ensure all fuel connections are properly secured and leak-free before operating the vehicle.
-
Additional injectors or other fuel-system upgrades may be required for higher ethanol concentrations and increased power targets.
-
Fuel-system requirements depend on the ethanol percentage, engine configuration, and calibration. Confirm the necessary supporting hardware with COBB Tuning or your tuner.
-
Follow the manufacturer's installation and tuning instructions.
-
Professional installation is recommended because the kit involves fuel-system connections and vehicle electronics.
