Guide to Motorcycle Fuel Pumps

The motorcycle fuel pump is a complex piece of technology that can be intimidating for novice riders and experienced veterans alike. Whether you’re just starting out or looking to upgrade your ride, understanding how these pumps work is essential if you want to stay on the road. 

So what exactly are fuel pumps?

Well, in short, motorcycle fuel pumps are responsible for delivering gasoline from the tank to your engine—it’s that simple.

But there’s more to it than meets the eye with this integral part; various models have different features and specifications that make them better suited for certain types of bikes over others. 

We’ll take a deep dive into all things related to the fuel pump so you can hit the road with confidence knowing your bike is running smoothly.

What is the fuel pump?

The fuel pump is a device that brings gas from the tank to your engine.

It works in conjunction with other components such as the carburetor, injectors, and ignition system to ensure the proper operation of the bike.

Fuel pumps can be mechanical or electric and they come in different sizes depending on the make and model of your bike.

Motorcycle pumps are typically located on the left side of the engine and consist of a fuel line, filter, and outlet for gasoline to be delivered. It is important to keep the fuel pump clean as contaminants can reduce its efficiency or even cause it to fail prematurely.

How does a motorcycle fuel pump work?

The basic purpose of a fuel pump is to supply your engine with enough gas at the right pressure and volume.

When you turn your key, the fuel pump will activate, sending fuel through an inlet valve and into a chamber where a diaphragm then pushes it onto the outlet side of the device. This process continues until the desired amount of gas has been provided to your engine. 

The pressure created by this process helps ensure that whatever type of fuel your bike uses can be safely and efficiently delivered to the engine. 

What Are the Different Types of Motorcycle Fuel Pumps?

The type of motorcycle fuel pump you will need depends on your bike’s make, model, and overall design.

Mechanical fuel pumps are the most common type for older bikes, but more modern machines typically rely on electric models due to their ease of installation and maintenance. Additionally, many newer bikes come equipped with pulse-type fuel injectors that require a specific pressure-regulated pump in order to work correctly. 

No matter what type of motorcycle you have, it is important to use a high-quality OEM (original equipment manufacturer) fuel pump that is specifically designed for your bike. This will ensure the right level of pressure and volume is supplied to your engine, so you can get the most out of it. 

Symptoms of a Bad Motorcycle Fuel Pump

Due to the critical role fuel pumps play in an engine’s operation, it is important to be aware of any signs or symptoms that indicate yours may be failing.

The most common symptom of a bad fuel pump is difficulty starting your bike, as this could mean the pump is not providing enough pressure for gasoline to properly reach your engine. 

Other signs include:

• Hard shifting between gears.
• Sputtering when accelerating.
• Loss of power while riding.

If you notice any of these issues with your bike, it’s best to have a professional inspect your fuel pump and make sure it’s functioning correctly. 

Fixes & Estimated Cost

Of course, the cost of replacing your motorcycle fuel pump will depend on the type and model you need.

Generally speaking, a mechanical fuel pump can range from $100 to over $300 while electric models may be more expensive due to their higher level of complexity. 

Many manufacturers offer incentives such as extended warranties on new parts or discounts on repairs if you purchase the necessary components from an authorized dealer. It’s a good idea to research the available options beforehand, so you can make an informed decision on which fuel pump is right for your motorcycle. 

With the proper maintenance and care, your motorcycle fuel pump should last a very long, giving you plenty of time to enjoy your bike on the open road.

Keeping it clean and replacing any worn-out components as needed will help extend its lifespan even further.
