FiTech Ultimate LS Truck EFI 750 HP Fuel Injection Systems with Hy-Fuel

FiTech Ultimate LS Truck EFI 750 HP fuel injection systems with Hy-Fuel thoroughly ease the process of adding fuel injection. They fabricated many billet aluminum parts for these systems, including a 102mm 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 66 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.

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. For quick response and incredible abilities, install FiTech Ultimate LS Truck EFI 750 HP fuel injection systems with Hy-Fuel.
