Harley Davidson Motorcycle Fuel Pumps & Components

The V-Twin motor of your Harley Davidson produces horsepower by burning gasoline mixed with air. In earlier models, this mixture is produced in carburetors. To ensure a constant flow of fuel from the tank to the carburetor, a low-pressure pump is used. It uses the vacuum created in the crankshaft when the engine is running. Vacuum operates the rubber membrane inside the pump that sucks gasoline from the tank and sends it into the carburetor. In modern models equipped with the fuel injection system, the higher pressure of the gasoline is needed. For this reason, a high-pressure electric pump is used.

An electric pump is usually incorporated into the gas tank where it remains protected from high-temperature damage. The pressure is regulated by the electronic engine control module depending on the load. It can also shut down the flow of gasoline to the motor in case of a crash to prevent fire. If you find that your carburetor or fuel injectors do not receive enough gasoline, it is time to check your pump and replace it if needed. Our online store offers a wide range of electric and mechanical Harley Davidson fuel pumps and related components, such as pressure regulators, check valves, fuel pump connectors, primer bulbs, and so on.
