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 everyting needed to convert factory or aftermarket EFI systems into a complete FAST® EZ-EFI® Fuel system.

The wiring harness is completely pre-wired and labeled for a simple installation. It includes connectors compatible with early style GM® sensors (coolant temp, air temp, TPS, MAP and IAC) such as those found on a Tuned Port engine. All of these sensors are available from FAST® individually or in kit form. FAST® also offers a Ford® style TPS that is directly compatible with the harness. Or the harness can be modified to accept any 0-5V TPS. The rest of the sensors need to be GM® style parts. Wiring adapters are available from FAST® to accommodate a later style GM® TPS (round, 3 pin connector) or IAC (in-line, 4 pin connector). Also available are a remote mounted IAC kit and an adapter for installing an early GM IAC on a Ford® throttle body.

The harness is wired for eight traditional "Minitimer" style injectors. Injector adapters or connector kits are available from FAST® to adapt the harness to newer "USCAR" style injectors. The EZ-EFI® system must be used with high impedance injectors. A wide range of high impedance injectors are available from FAST®.

The EZ-EFI® system must be used with a vacuum referenced fuel pressure regulator. Returnless fuel systems can not be used. FAST® offers an adjustable regulator that is ideally suited for use with EZ-EFI®. Various fuel system kits are also available.
