How To Clean Motorcycle Fuel Pump

If you own a motorcycle, you probably know how much of a pain it can be to maintain it. It’s not like driving your average car, where you check the oil and gas levels once in a while and everything is good to go. When you have a bike, there are so many places that require special attention or maintenance.

These little machines are quite sensitive when it comes to the right fuel mixture and air supply. And something as simple as clogged fuel filters or contaminated fuel lines can cause your bike to break down at the most inconvenient times. That’s why knowing how to clean motorcycle fuel pump is important for keeping your bike in tip-top shape. Even if your bike has an automatic engine with no manual transmission, engines are very sensitive machines that need special care from their owners if they want them to last more than 100K miles.

What’s the Difference Between Manual and Automatic?

Before we go any further, let’s make sure you understand the difference between the two types of fuel pumps. Fuel pumps are responsible for transferring fuel from the fuel tank and into the engine. There are two types of fuel pumps: Manual pumps are usually found on older motorcycles. These pumps are driven by the engine itself, meaning they spin at a constant rate and pressure while the engine is running. Manual pumps are easier to clean than automatic pumps, although both will be covered below. Automatic pumps are often found on newer vehicles or those that have been modified. These pumps are driven by the pressure of the fuel itself, meaning they spin faster when more fuel is needed and slower when less fuel is needed. Automatic pumps are more complex and difficult to clean, but they also have an in-line fuel filter that older models may not have.

When Should You Clean the Fuel Pump?

The best time to clean your fuel pump is before you have a problem. Fuel filter blockages and pump clogs happen to almost every vehicle owner at some point in their lives. The best way to avoid this is through preventative maintenance. The fuel pump and fuel filter are usually located on the lower portion of the engine. In order to clean the fuel pump, you need to remove the fuel filter and fuel pump from the engine. This can be a bit of a pain and can vary from model to model, so make sure you get the correct manual for your bike. Generally, you should clean the fuel pump once every year in spring before the motorbike season gets into full swing. This will ensure that your engine is prepared for the harsh conditions of the road and that nothing will go wrong during your travels.

How to Clean a Fuel Pump: Step by Step

There are a few things you should do before you get started. Make sure you have a clean and well-ventilated area to work in, preferably outside. It’s not a good idea to use a pressure washer inside because of the fumes. First, remove the fuel pump from the motorcycle. Most models have a plug that can be removed with a screwdriver. You can follow the fuel lines to see where these plugs are located. Next, check the fuel pump for corrosion. If you see any corrosion, you can clean the pump with a mixture of water and baking soda. Remove the fuel filter and check it for buildup as well. If the filter is clogged, you can clean it with a toothbrush and some carburetor cleaner.


Motorcycles are special machines that need a lot of care and attention. They are sensitive and delicate, and every part of them must be kept clean and maintained regularly.

That’s why it’s important to keep your fuel pump clean and in good condition. If you follow the steps laid out in this article, you’ll be able to clean your fuel pump and make sure your engine is ready for any challenge.
