Fuel Injection

Harley-Davidson fuel injection systems electronically control fuel delivery to the engine, using components such as fuel injectors, throttle bodies, fuel rails, sensors and fuel pumps to manage the intake and fuel supply system. This category includes Harley-Davidson fuel injection parts, electronic fuel injectors, fuel pump assemblies, fuel pump modules, fuel pressure regulators, fuel rails, throttle bodies and EFI control components. Harley-Davidson service information identifies injectors, fuel rails, throttle bodies, throttle-position sensors, idle-air-control components and fuel pressure regulators as parts of EFI systems.

The product range covers Harley-Davidson fuel injectors, high-performance injector sets, fuel pump kits and modules, EFI fuel lines, fuel filters, check valves, fuel pressure regulators, injector O-rings, intake manifold seals, oxygen sensors, MAP sensors, throttle-position sensors and throttle bodies. Electronic control and tuning products are also represented, including EFI engine management systems and fuel-injection controllers. Harley-Davidson fuel pump assemblies can include filters, hoses, wiring, connectors, seals and related tank hardware, making these components relevant for both replacement and fuel-system service.

Fuel injection fitment varies by motorcycle model, engine configuration, EFI generation, injector type, fuel-pump arrangement, throttle-body design and electrical connections. The selection covers applications for Sportster, Dyna, Softail, Touring, Twin Cam and Milwaukee-Eight motorcycles, along with replacement and performance components for different EFI configurations. Matching Harley-Davidson EFI fuel injectors, fuel pump assemblies, throttle bodies, oxygen sensors and related components to the specific motorcycle and original system helps ensure the correct connections, mounting arrangement and fuel-delivery specifications.
