Description

One of the issues with adding an EFI system is the need to run a noisy external fuel pump, but FiTech Ultimate LS Truck EFI 500 HP fuel injection systems with Hy-Fuel module eliminate this issue. Hy-Fuel in-tank modules can be run as either returnless or return-style by use of the 3-bar regulator or block-off. They feature a unique baffling system, making it easy for fuel to enter, but difficult to leave, even under hard corners, bumps, and moderate off-road adventures. They can be added to new or existing fuel tanks.

FiTech fabricated many billet aluminum parts for these systems, including a 92mm throttle body, high-volume fuel rails, and a 1,500 to 6,500 rpm powerband intake manifold. They combine sequential spark and fuel control with 36 lbs./hr. injectors, a plug-and-play wiring harness, and a color touch-screen, self-learning ECU. This allows for programing two fan control outputs, most tach and speedometer output drivers, and target AFR and timing on the fly. Keep your pump cool and quiet while cruising or flying by installing FiTech Ultimate LS Truck EFI 500 HP fuel injection systems with Hy-Fuel.

Additional EFI features:

* Optional GM transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80
* Black anodized aluminum parts for style and corrosion resistance
* High-flow, cable-operated throttle body
* Bosch wideband-controlled

* Available with 340 lph (89 gph) fuel pump supporting up to 800 hp
* O-ring style 360 degree mounting flange for ease of maintenance
