It gives you the total package to easily bolt on to any 4150-type manifold and comes with everything you need, including the appropriate fuel injectors and fuel rails.

Works On Your Engine – No Manifold Or Extra Parts Needed
Regardless of your brand or size, this system bolts on easily to any carbureted engine making up to 650 horsepower – NO manifold replacement is needed. In addition to matching any carbureted manifold, the EZ-EFI® Self Tuning Fuel Injection System also works with your original carb-style throttle linkage and is ready to accept all OEM sensors, including standard GM versions available at any auto parts store. It does not require proprietary sensors that are only available from the system’s manufacturer. What’s more, EZ-EFI® works with all ignition setups – including HEI. The EZ-EFI® can be installed easily in an afternoon and is a "must have" for your street rod or muscle car. FAST™ invented and perfected self-tuning EFI, don’t settle for imitators.

An EZ Solution For Any Setup
For more aggressive applications, the EZ-EFI® Dual Quad Upgrade Kit is capable of supporting 1200+ horsepower engines with dual quad carburetor-type manifolds. In addition, the Multi-Port Retro-Fit EZ-EFI® allows owners of multi-port fuel injected applications to experience the benefits of EFI with no limit on horsepower because the system is based on each customer's supplied injectors. Unlike competitors’ systems, the EZ-EFI® is readily available in dual quad or eight stack induction systems. Meanwhile, the new EZ-EFI® Jeep Kit with inline or in-tank fuel pump kit is engineered specifically to work with the unique requirements of 1972-1991 Jeep CJ/YJ 4.2L, 6-cylinder applications.
