Cleaning your car's fuel system is an important part of vehicle maintenance. Deposits from the combustion process, dirt and debris from pump nozzles and filler caps, and general wear and tear can all contribute to a dirty fuel system. This can lead to clogged injectors, inefficient combustion, and reduced fuel economy. To clean your fuel lines, you can use a variety of methods such as compressed air, acetone, or commercial fuel system cleaners. Some people also recommend using a bicycle or tyre pump to unclog the lines. It is important to clean your fuel lines regularly to ensure optimal engine performance and fuel efficiency.

What You'll Learn
Using compressed air
Cleaning fuel lines is an important step in ensuring optimal fuel economy and smooth engine performance. It also helps to prevent rust, debris, and other contaminants from entering the combustion chamber, which could lead to engine failure. While it is recommended to seek professional assistance, as it involves handling highly flammable substances, those comfortable with car parts may use compressed air to clean their fuel lines.
First, disconnect the fuel line from the fuel pump. This will allow you to blow air through the line more effectively. You may want to replace your rubber line with a 30r9 (fuel injection hose) or 30r14 barricade line, as these are better than the standard 30r7.
Next, blow compressed air through the line from the tank end. This will help to clear any debris or blockages. Be careful not to blow with too much force, as this could damage the line or the pump. You may also want to check the pickup line and tube for any rust or debris, as these can become clogged and affect the fuel flow.
After blowing through the line, crank the engine and let the fuel pump prime itself. This should only take about 30 seconds. Be fire-ready, as there is a risk of flammability when working with fuel lines. It is also recommended to change your fuel filters a few times after driving to ensure that any remaining debris is cleared.
Finally, inspect the fuel line for any signs of damage or wear. If the line is damaged, it may need to be replaced. It is also a good idea to check the fuel tank and sender for any issues, as these can also impact the fuel system's performance.

Pouring in acetone
Pouring acetone into your fuel tank is a great way to clean it out. Acetone is a powerful solvent that can dissolve old gas, varnish, and other gunk in your fuel system. It is also relatively safe, as it has a neutral pH of 7, and is a common ingredient in many carb cleaners.
However, acetone is quite aggressive and can be harmful to your skin, lungs, and paint/finish surfaces. It can also dissolve cheap plastics, so it should be used with caution. When using acetone to clean your fuel lines, it is important to follow the directions on the product carefully.
To use acetone to clean your fuel lines, start by pouring it into your fuel tank. You can either pour it directly into the tank or add it to your fuel. If your fuel lines are extremely clogged, you may need to remove the fuel lines and soak them in acetone separately. You can also try adding a small amount of acetone to a quarter tank of gas and running it through your engine, which may help dissolve any built-up varnish or gunk.
After using acetone to clean your fuel lines, it is important to dispose of it properly. Acetone will evaporate on its own, but it is recommended to pour it into another container first so that any dissolved sludge does not remain in your fuel tank. Do not pour acetone down the drain or onto the ground, as it can be harmful to the environment.

Using a petroleum-based solvent
One way to clean your fuel lines is to use a petroleum-based solvent. This method is effective at removing carbon deposits and gunk from inside engines and fuel systems. Seafoam is a petroleum-based solvent that can be used for this purpose.
To use Seafoam, fill your tank with gasoline and pour in a bottle of Seafoam. For every bottle of Seafoam, you will need about 3 gallons of gasoline. Let the engine idle, and do not put any load on it. As the fuel pump pulls fuel from the tank to the engine, the Seafoam will mix with the gasoline and start to break down the crud in the lines. This will expose the crud to the Seafoam, allowing it to be broken down and removed from the fuel lines.
It is important to note that gasoline is highly combustible and can be dangerous. Always take the necessary safety precautions when working with fuel systems. Additionally, petroleum solvents have been known to raise environmental, health, and economic concerns due to the volatile organic compounds (VOCs) and other chlorinated solvents they contain. As a result, many businesses are switching to aqueous parts washers, which are water-based cleaners that are non-flammable and contain little to no VOCs.
However, if you choose to use a petroleum-based solvent like Seafoam, it can be an effective way to clean your fuel lines and improve the performance of your engine. Just be sure to also replace your fuel filter and inspect your gas tank for any sediment, rust, or holes that may be causing issues.

Cleaning with Redex
Cleaning your car's fuel system with Redex is a straightforward process. Redex is a fuel additive that can be used to clean your car's tank, fuel lines, and injectors without causing any damage. It is safe to use in most petrol engines, including those with new E10 fuel, and will not cause any ill effects even if you add too much. The product is designed to be easy to use, with clear labelling showing how much to use for different fuel tank sizes.
To clean your fuel lines with Redex, simply pour it directly into your fuel tank. It can be added before or after filling up with fuel and can be used with any type of fuel. The recommended dosage is 2.5ml of Redex System Cleaner per litre of fuel. This equates to half a shot for a 15-litre motorbike fuel tank. However, it is important to note that you should not exceed four times the recommended dosage, as this could be harmful.
Redex fuel additives are suitable for use in cars, vans, motorbikes, tractors, or any vehicle with a petrol or diesel engine, including hybrids. They are also safe to use in vehicles with exhaust treatment systems such as AdBlue® or a lean NOx trap. In addition to the standard Redex System Cleaner, there are also specific products available, such as the Redex DPF Cleaner, which helps to clear soot buildup and prevent blockages in the DPF filter.
Using Redex to clean your car's fuel system can offer several benefits. It can help improve fuel efficiency, boost engine performance, and reduce emissions. It can also prolong the life of your engine by preventing clogged injectors and ensuring optimal combustion. Regular use of Redex can be a simple and convenient part of your car maintenance routine, keeping your vehicle running at its best.

Flushing the lines
One option is to use a petroleum-based solvent, such as Seafoam, which can be poured directly into the fuel tank. For every can of Seafoam, it is recommended to use 3 gallons of liquid, which will help to break down the deposits in the fuel line and clean out injectors. Let the engine idle, and as the fuel pump pulls fuel from the tank to the engine, the Seafoam will start to break down the crud in the lines, improving the flow of gasoline.
Alternatively, you can use acetone, which completely evaporates and leaves no trace behind. Pour the acetone into the line and tape a rag loosely to the other end, then blow it through. Repeat this process until what comes out is clean and clear.
Compressed air can also be used to blow out the lines, but it is not as effective as using a liquid to flush the system. If using compressed air, it is recommended to also use a liquid cleaner to ensure the lines are thoroughly flushed.

Frequently asked questions
Compressed air is the best way to clean fuel lines. You can also use a petroleum-based solvent, such as Redex, Seafoam, or acetone, to remove carbon deposits and gunk from inside engines and fuel systems.
Deposits block up the injectors so that fuel isn't sprayed efficiently, causing MPG to decrease and emissions to rise. If you notice these issues, your fuel lines likely need cleaning.
While you don't technically have to clean your car's fuel system, it is good practice to do so regularly, as it will help keep your car running efficiently and ensure you're getting the most from every litre of fuel.
Cleaning your fuel lines can help prolong the life of your engine, improve fuel economy, reduce emissions, and boost performance.
