All About the Harley-Davidson Sportster Fuel Pump Assembly Replacement


This in-tank EFI (Electronic Fuel Injection) fuel pump assembly is a direct replacement for OEM parts like 75305-07A and 75268-07F (also known as HFP-A250 in some listings). It's a complete module featuring a high-efficiency pump motor (often called the "pump core" in aftermarket terms), pressure regulator, fuel filter, strainer, fuel level sensor, and wiring harness with a 4-pin connector. The assembly is built with durable metal and plastic components, including upgraded polymers for corrosion resistance and quiet operation.


Key physical highlights include:


  • A compact design with a black plastic mounting flange, metallic pump body, and flexible fuel lines.

  • Integrated components like a pickup screen, relief regulator, and clamps for secure internal tank mounting.

  • Multi-colored wiring (typically red, black, yellow, and others) for easy electrical hookup.

  • Overall lightweight build at around 9.6 oz (272 grams) for the core assembly, making it easy to handle during installs.


This part is ethanol-compatible (up to E10 blends) and engineered for over 100,000 miles of reliable service, with patented check valve technology to prevent backflow and ensure consistent performance.



Product Specifications


Here's a breakdown of the key specs to help you assess fit and function:


  • Model/Part Numbers: Compatible with OEM 75305-07A, 75268-07F, HFP-A250; aftermarket equivalents like OSIAS OT75268-07F or QFS HFP-A250.

  • Fuel Type: Unleaded gasoline, compatible with up to 10% ethanol (E10).

  • Power Source/Electrical Input: 12V DC from the motorcycle's battery/electrical system; draws low amperage for efficient operation.

  • Output Fuel Pressure: Regulated to 55-62 PSI (3.8-4.3 bar) for optimal EFI performance; some listings note 40-60 PSI range.

  • Flow Rate: 118-152 liters per hour (LPH) at rated pressure, ensuring ample supply for stock or mildly modified engines.

  • Materials/Construction: Metal pump body, plastic housing and flange, rubber seals, and corrosion-resistant internals.

  • Installation: Drop-in replacement via the tank's access plate; requires draining the tank, disconnecting quick-fittings, and basic tools like screwdrivers and pliers. Professional install recommended if unsure.

  • Maintenance: Replace filter every 10,000-20,000 miles; check for clogs or leaks annually; drain tank for long-term storage to avoid gumming.


How It Powers Your Harley-Davidson Sportster


The fuel pump assembly is the heart of your Sportster's EFI system, drawing gasoline from the tank and delivering it under pressure to the injectors for precise combustion. It's mounted inside the fuel tank for a clean, integrated setup and includes a fuel level sensor that feeds data to your dash gauge.


Here's how it fits in:


  • Reliable Fuel Delivery: Provides steady pressure and flow to prevent lean conditions, especially during hard acceleration or low-fuel scenarios—common issues on aging bikes.

  • Application Scenarios: Ideal for daily commuters, weekend cruisers, or custom builds on models like the XL883 Iron or XL1200 Forty-Eight. It supports the Evolution engine's 883cc or 1200cc displacements, ensuring quick starts and smooth throttle response.

  • Extended Durability: With features like a built-in pressure regulator and strainer, it handles modern fuels without seizing, extending your ride time and reducing breakdowns.


If symptoms like hard starting, power loss, or check engine lights (e.g., codes related to fuel system) pop up, this assembly is often the fix. It's a straightforward swap that can be done in your garage, as shown in various DIY tutorials.
