FAST XFI Fuel Injector Harnesses connect the XFI ECU to the fuel injectors. These harnesses are designed to accommodate most common V8 engines from the Chevrolet Small Block to GM LS Series, Ford Small and Big Blocks as well as Windsor, Modular, FE configurations. FAST also has taken the initiative to help out customers with less common applications such as Buick V6, Modern Chrysler and even 4 cylinder applications. And, while we may not have a custom tailored injector harness that fits your needs, all of our harnesses can be re-pinned for custom firing orders and reterminated to accommodate different injector connectors.

Fuel delivery is an important aspect to every vehicle. Having a proper fuel supply is vital to your vehicle's performance and reliability. Get your ride set up with fuel products from the best brands in the industry.

If your vehicle's fueling system is incomplete, complete it with a quality set of fuel components.
