Description

FiTech Go EFI 2x4 625 hp system fuel injection master kits are inclusive EFI kits with fuel delivery solutions. In these master kits, FiTech mates their 2x4 TBIs with either a Go Fuel in-tank or fuel cell pump module, or Go EFI in-line pump kit to provide everything needed to convert your carbureted vehicle to EFI. The throttle bodies are offered in two finishes. Choose the master kit with your preferred finish and fuel delivery solution.

Go EFI 2x4 625 hp system lets everyone know you mean business with a pair of 4-barrels crowned atop your engine! The 2x4 is supplied with two throttle bodies, one with the brains and integral ECU, the other with the brawn. Both bodies feature four injectors and will support up to 625 hp (naturally aspirated). The system is supplied with two throttle bodies, handheld controller, cable and windshield mount, throttle body vehicle side harness, WBO2 sensor, bung kit, coolant sensor, gasket, mini USB cable, instructions, and warranty information.

Fuel delivery options:

* Go Fuel in-tank pump modules are offered in different styles, including regulated versions, and in different flow rates. They include gaskets, terminals, and clamps.
* Fuel cell pump modules are offered in two models—single or dual pump. Each style features a billet machined top assembly and an internal regulator to maintain 58 psi. No return line is needed, and the module is machined to fit 12-bolt flange fuel cells or can be installed on any tank with the supplied hardware.
* Go EFI in-line pump kits provide a FiTech heavy-duty pump with 40 ft. of high-pressure fuel hose, two fuel filters, including a serviceable 10-micron filter, fittings, mounts, and clamps.
