- FAST EZ-EFI Multi-Port Retro-Fit Kit
The EZ-EFI Multi-Port Retro-Fit Kit allows owners of existing factory or aftermarket multi-port fuel injected applications to experience the benefits of an EZ-EFI Fuel system with no limit on horsepower because the system is based on each customer’s supplied injectors. The kit comes with everything needed to convert factory or aftermarket EFI systems into a complete FAST EZ-EFI Fuel system. The wiring harness is completely prewired and labeled, includes connectors for early-style GM sensors as found on GM Tuned Port Engines (coolant temp, air temp, TPS, MAP, and IAC). The harness is wired for eight traditional Minitimer-type injectors. Injector adapters or connector kits are available to adapt the harness to newer USCAR-type injectors.

The EZ-EFI System must be used with high-impedance injectors, a vacuum-referenced fuel pressure regulator. Returnless fuel systems cannot be used.
