Best Fuel Injector Cleaning Kit (Review & Guide) 2020

In these modern times, a dirty fuel injector system is a common problem for vehicles. Most of the vehicles you see on the road today are electronic fuel injection systems, with the exception of the carbureted and direct injected vehicles. The electronic fuel injection systems distribute your engine’s fuel through an electronically controlled fuel injector system.

Most injections work by spraying a fine and specific pattern of mist into your engine. This system is important for the correct and healthy operation of your vehicle’s engine. Over time, the nozzles that are spraying the fuel might become clogged and dirty from deposits that are found in your engine’s fuel.

This is where a fuel injector cleaning kit comes in handy, but which ones are the best ones to use, and how do you use one?

Fuel Injector Cleaning Kit Buying Guide

Using a fuel injector cleaner system is not an easy task. When the fuel injectors become clogged or too dirty, they will no longer distribute the fuel correctly, and this is going to make your engine’s performance less than satisfactory, and it could even cause some emissions problems.

That is why we focused on writing this cleaning kit or system to help you in making a good decision when it comes to making the best purchase possible.

How to Use a Fuel Injection Cleaning Kit

First, you’re going to need an air compressor, hand tools, a fuel injection cleaning kit, and some safety glasses. You should thoroughly read the instructions for your kit before you use it.

Find the connector

The first step to cleaning your injection system is to locate the connector. You can find where it’s located in your vehicle’s user manual, or look it up on the car manufacturer’s website.

Warm up the engine

Second, you’re going to want to warm up your engine. Once you’ve found where you’ll connect the kit, start your vehicle and let it run until it’s at its normal operating temperature. Take note that some cleaning kits require the vehicle to be at a certain temperature, so be sure you read the instructions.

Turn off your vehicle and disable your fuel pump.

Add fuel injector cleaning solution to the kit

Then prepare the cleaning solution. If the cleaning kit doesn’t come filled with a solution, you’ll need to add your solution to the canister.

Prepare the cleaning kit by connecting it to the engine with the hoses and fittings. For most kits, you’ll see the pressure and make adjustments as you need to.

Connect the cleaning kit

Connect the fuel system cleaning kit to the fuel system in your vehicle at the connector. If your vehicle doesn’t use a threaded fitting, take precaution when you’re alleviating the fuel pressure before you open up your system.

Attach the compressed air hose

The tool works by using the compressed air to power your kit and distribute the solution through the vehicle’s injection system.

Match the pressure of the cleaning tool and your system. The pressure has to be equal so that when the valve opens, the solution flows through the same way the fuel normally would.

Then, prepare to start the engine. Once the regulator is at the right pressure, open the shut-off valve and start your engine. Run it for the specified period in the cleaning kit’s instructions.

Disconnect the kit

Turn off your vehicle and disconnect the kit. Then, reinstall your relay, and you’re finished!
