bootmod3 FlexFuel Kit - High Flow
Add flex-fuel hardware to your compatible BMW or A9X Toyota Supra with a kit that connects directly to the factory wiring. Installation requires no cutting or splicing of OEM wires or connectors, and the system can be removed to return the vehicle to its original configuration.
Pair the hardware with a flex-fuel-enabled bootmod3 OTS MultiMap or a custom map from your bootmod3 tuner. The CANBUS ethanol content analyzer communicates with bootmod3 CustomROM to support flex-fuel operation.
High-flow sensor adapter
The Flow Optimized Flex Fuel Sensor Adapter (FFSA) uses a three-piece 6061 aluminum housing and an integrated sensor bypass. Its design maintains unrestricted fuel delivery without adding pressure drop at full pump flow. Fuel-safe Viton O-rings seal the connections.
For the OEM fuel-hat configuration, the housing fits in the factory fuel-hat area beneath the rear seat. Two 1/8 NPT ports provide mounting options for an auxiliary fuel-pressure sensor on vehicles without a factory sensor, with support through bootmod3 CustomROM v2. Choose the port that suits your installation.

Select the correct installation location
Choose the vehicle, engine generation, and installation location that match your car from the Vehicle Engine Type menu.
OEM fuel-hat kits require the factory fuel pump and its associated wiring. Modified fuel pumps or fuel lines may prevent fitment. If your fuel system has been changed, choose an engine-bay kit where one is offered for your vehicle.
