Take your Kia Stinger and Genesis 3.3L twin-turbo V6 fueling system to the next level with the Fuel-It! Port Injection Kit with Ethanol Content Analyzer. Designed for high-output builds running E85 and ethanol blends, this comprehensive fueling solution adds six secondary port fuel injectors and the supporting fuel-system hardware needed to provide substantially greater fueling capacity.

Fuel-It! designed the system around the demands of heavily modified 3.3T applications, combining six flow-matched 750cc DeatschWerks injectors, an auxiliary low-pressure fuel pump, fuel filter, pressure regulator, dedicated fuel lines, billet fittings, and an integrated ethanol-content sensor. The complete system is designed to support applications producing over 900 WHP on straight E85, according to Fuel-It!'s testing and specifications.

Expanded Fueling for High-Boost 3.3T Builds

As power levels increase, the factory direct-injection fuel system can become a limiting factor, particularly when running high ethanol-content fuels and increased boost.

The Fuel-It! Port Injection Kit supplements the factory fueling system with six additional port-mounted fuel injectors, increasing the engine's available fuel capacity and providing the additional headroom required by high-output applications.

The kit uses a set of six flow-matched DeatschWerks 750cc fuel injectors. Fuel-It! specifies the injectors as capable of supporting over 900 HP, making the system well suited to serious 3.3T performance builds.

Complete Secondary Fuel System

Rather than simply adding injectors, Fuel-It! provides the supporting components required to maintain consistent fuel delivery.

The kit includes a Walbro 450 E85-rated auxiliary fuel pump, capable of supplying up to 450 LPH at 40 PSI according to the manufacturer. The pump is designed for use with both gasoline and ethanol-based fuels and works with either the factory fuel-pump bucket or Fuel-It!'s Stage 2 setup.

Additional fuel-system components include:

• Auxiliary low-pressure fuel pump
• Fuel filter
• Pressure regulator
• Fuel lines
• Billet fuel fittings
• Heavy-duty gaskets
• Wiring
• Installation hardware
• Plug-and-play BMS braided fuel-line connections
• JB4PRO port-injection harness

This complete approach helps provide consistent fuel delivery when the engine is operating under increased boost and fuel demand.

CNC-Machined Billet Aluminum Port Injection Spacer

At the heart of the system is Fuel-It!'s CNC-machined billet aluminum port injection manifold spacer.

The spacer is designed for factory-like integration with the 3.3T engine while providing the mounting location required for the six additional injectors. It is finished in black anodizing for durability and a clean appearance within the engine bay.

The result is a purpose-built port injection solution that integrates additional fueling capacity without relying on improvised mounting or universal components.

Integrated Ethanol Content Monitoring

This version of the Fuel-It! kit includes a genuine Continental ethanol-content sensor, allowing the fuel system to monitor the actual ethanol concentration in the vehicle's fuel.

This is particularly valuable for vehicles running E85 or varying ethanol blends, where the actual ethanol percentage can differ between fuel stations and batches.

The ethanol sensor works with the BMS CANflex ECA and JB4PRO system, allowing ethanol content to be monitored through the associated electronics and used as part of the vehicle's tuning strategy. Fuel-It! notes that the included ethanol sensor is required with this kit because its fuel-line routing differs from the existing Kia flex-fuel sensor setup.

JB4PRO Integration

The Fuel-It! Port Injection Kit requires a JB4PRO system for port-injection and secondary fuel-pump control. The required JB4PRO add-on PI harness is included with the kit.

For properly configured applications, the JB4PRO system can utilize the ethanol-content information from the Continental sensor as part of the vehicle's tuning strategy.

This makes the system particularly well suited to enthusiasts who want to combine supplemental port injection, ethanol fueling, and electronic fuel-content monitoring in one integrated setup.

Built for E85 and Ethanol Blends

The additional fueling capacity makes the Fuel-It! system particularly useful for high-output applications running E85 or ethanol blends.

Ethanol fuels require greater fuel volume than gasoline to produce the same power, making adequate injector and fuel-pump capacity especially important as boost and horsepower increase.

By combining six additional 750cc injectors with an auxiliary E85-rated fuel pump and real-time ethanol monitoring, the Fuel-It! system provides a comprehensive foundation for high-power ethanol-fueled 3.3T builds.
