How to Use Fuel Injector Cleaners? 2021 Step By Step Guide

Fuel injection systems are different since each is calibrated for a particular type of fuel. A crack in fuel injectors can result in fuel leak, which can cause to pay more for the gas. Faulty injectors can restrict the flow of the fuel, which can cause the engine to misfire.

Fuel inject cleaners are unique solvents that are directly mixed with the fuel pumped into the tank. Despite assurances from the fuel-producing companies, the fuel provided is never 100% pure. It contains additives mostly compromised during the storing process.

These can cause thick materials to stick to the gas tank hence reducing its capacity. Injector fuel cleaners usually dissolve the impurities and are burned away during the combustion process with the fuel.

How to Use Fuel Injector Cleaners

How to use fuel injector cleaners? In 9 Easy Steps

Step 1: Purchase injector cleaner kit with a cleaning fluid

Purchase an injector cleaning kit that suits best for your vehicle. Each cleaner kit should must come with a canister of the right fuel injector cleaner and a good hose attached to the fuel injector and rail. You should opt for cleaning fluid, which contains PEA for the best results, which dissolves thick carbon deposits effectively than other ingredients.

Step 2: Review the vehicle’s engine layout to find the fuel injector.

Different vehicle types have different engine layouts, so it may be hard to locate your fuel injectors. Look at your vehicle’s manual to find the fuel injectors. You can do some research online that may help you locate the fuel injectors.

Step 3: Remove the fuel pump from the fuel injector.

Disconnect the pump, which is located on the side of the engine. Pull out the fuel injector gently to detach them from the fuel pump. Once you remove them, you should connect the fuel return line to the fuel pump to allow the gas inside to return to the tank as you clean the injectors.

Step 4: Disconnect the pressure regulator vacuum line

Find the fuel pressure regulator if you have one and check the vacuum line attached to it. Brace the pressure vacuum line just above where it connects to the regulator. Pull it out carefully to disconnect it.

Step 5: You need to connect the cleaning kit to the fuel pressure port.

Find the fuel pressure port, which is attached to the fuel rail in your car engine. Follow the guideline in the cleaning kit to connect the hose and fitting to the port. Ensure that the component is attached to the horse and the port. Ensure that the injectors have no exposure to the fuel because the cleaners are flammable.

Step 6: Remove the fuel tank’s cover.

Be sure to remove the tank cap before beginning to clean for avoiding the excessive pressure created due to debris cleaning. This happens because the cleaner removes debris and grime by using a burst of pressure to inject the cleaning solvent into the injectors. This may create excessive pressure which could burst into flame.

Step 7: Turn on your car engine to let the cleaner into your injections.

Ensure that the fuel pump is turned off. Turn on your car engine and let the engine run. Usually, the engine will stop running once the cleaning solvent is all used up. The approximate time for the cleaner to cycle through the fuel injectors and get used up is 5 to 10 minutes.

Step 8: Now that the fuel injector is clean, detach the cleaning kit and remove the cleaner.

Detach the hose from the fuel port. Next, reattach the fuel pump and the vacuum hose that regulates pressure. Put the fuel tank cap back to its place. 

Step 9: Turn your engine on again and ensure that the injectors work perfectly.

Run a test to ensure you have reattached everything correctly. Pay attention to noise that could indicate a failure or any other problem. Drive the car for a short distance to ensure it runs smoothly.

Tips when using fuel injector cleaners

What causes the debris

Burned gasoline contaminates the fuel system and this leaves deposits at the bottom of the fuel tanks, around the fuel pressure regulator, or in the fuel lines. The problem is when the contaminants are deposited on the fuel injector. What causes the deposits? There are two leading causes of deposits build-up

Ethanol

Ethanol, as a renewable energy source, was used to reduce the amount of carbon (11) oxide emission. Thus, vehicles can comply with the terms of air-quality. Besides, ethanol was used as an ingredient for octane boosting.

New developed engines do not use ethanol for lowering fuel emissions. Instead, ethanol is used as a filler material to reduce gas costs. The engines are designed in a way they can run on ethanol. Older car engines are not accustomed to ethanol use.

Alcohol destroys the engine parts, especially if your vehicle uses the old engines, it will cause the dislodge of the carbon deposited particles. Additionally, the alcohol oxidizes and emulsifies to form a non-combustible mixture, resulting in a buildup in fuel injector.

Carbon

Carbon is the number one culprit for the harmful kinds of deposits in the engine. Vehicle engines are not able to extract all the energy from the fuel. The unused carbon deposits are harmful to your car engine.

Understand the fuel injector cleaners

Majority of the injector cleaners have the three chemical compounds discussed previously. You should check the injection clean to ensure it has the appropriate components. These components include;

Polyether Amine

Commonly called PEA, polyether amine is highly efficient eliminating deposits that impede the flow in cleaners. It breaks the bonds down of the deposits on a molecular level. Once they are removed from the injector walls, the disintegrated deposits are ejected through the vehicle when they pass through catalytic converters and the combustion chamber.

Polyisobutylene

This deposits from injector. Also, it can fix misfiring and residue-knock problems.

Polyisobutylene Amine

it works similarly to Polyisobutylene, except it works well with the moisture. However, it is mostly used for maintenance rather than the removal of long lasted solid deposits.

The quantity and frequency of use

The next step to know how to use injector cleaners is the quantity of use. Manufacture guidelines and instructions on the containers are mandatory. The volume of the cleaner in accordance with the capacity of the fuel tank depends primarily on the manufacturing details of the product and the guidelines provided on the manuals.

Different manufacturers manufacture their solutions differently. For some cleaners, the preferable volume of a twenty-gallon tank is a single-ounce bottle. It is always important to check the capacity of the tank before buying the fuel injector cleaner to abide with the laid out instructions from the manufacturer.

When it comes to how frequently you use the fuel injector, the ideal distance of travel before applying it is 10,000 miles. However, the condition of the tank may influence the distance.

Final Words

For effective results, ensure that you purchase one of the best fuel injector cleaners for your car engine. The best thing you can do is to research online and check reviews to check which cleaner suits best your car engine.

Since your car engine requires the utmost care and maintenance, you should not rely on any product. Ensure that the one you are choosing will work the best for your car.
