FiTech Retro LS TBI 650 HP System In-Tank Pump Fuel Injection Master Kits

FiTech Retro LS TBI 650 hp system in-tank pump fuel injection master kits deliver old school looks and modern EFI performance for your hot rod.

These kits feature a FiTech classic carburetor-gold throttle body with transmission control and a pre-terminated wiring harness with specific LS engine sensors, including the factory knock sensors to complement the built-in timing control. The remote ECU can control the transmission shift points and characteristics of the popular 4L60/65/80E transmissions. No laptop is required, and the system will work on 24x or 58x cam sensors. Also supplied with the Retro LS TBI is a handheld touch screen controller, cable and windshield mount, WBO2 sensor, bung kit, gaskets, mini USB cable, instructions, and warranty info.

For fuel delivery, these FiTech Retro LS master kits pair the TBI with a Go Fuel single fuel cell pump module—an ideal solution to your high-pressure fuel needs. It features a billet top assembly machined with a 2 in. filler assembly, as well as an internal regulator to maintain 58 psi. No return line is needed and the module is machined to fit fuel cells with a 12-bolt flange or can be installed on any tank with the supplied hardware.
