How to Clean Fuel Injectors

It is important to keep your vehicle’s fuel line as clean as possible.

This will help you run your car, truck, van, or another automobile much more efficiently and thus you will save on gas costs.

One very important part of the fuel line that needs to be clean occasionally is the fuel injector.

Of course, some knowledge of car maintenance is helpful.

However, it is never too late to learn this very important lesson on vehicle care.

Supplies Needed

To make your fuel injector project easier, you should purchase a few injector cleaning kits.

You can find them at an auto supply outlet, but they do cost $100. You are also going to need a screwdriver.

Steps to clean your fuel injector using the store-bought kit are basically described as below (and you can follow these unless the instructions provided in the kit are different:

  1. Either disable the fuel pump and plug the fuel return line or install a U-tube to force the fuel to return directly to the tank.
  2. Disconnect the pressure regulator and connect the cleaning kit to the fuel port located on the fuel rail.
  3. Replace the fuel cap. This will prevent excessive pressure buildup that is often characteristic of fuel injector cleaning.
  4. Make sure during this entire process that the engine will not turn over. Turn the ignition accordingly to prevent this from happening.
  5. Open and re-open the kit valve until the fuel pressure is measured at a rate appropriate for your vehicle. You should refer to your vehicle owner’s manual for more information.
  6. Start your vehicle’s engine. This will allow the cleaning solution to circulate through the injectors. Let your vehicle run until the solvent evaporates, which would be in about five minutes. At this time your engine should be shut down.
  7. Reset the fuel pump switch and replace the gas cap. After that, reconnect the pressure regulator and once again start the engine.
  8. Use the long screwdriver to detect rapid clicking sounds. This will ensure that your injector is operating properly.

Alternative Methods

For busy people who do not want to take the time to clean their own vehicle’s fuel injector, there is professional help.

For only about $40 you can have your fuel injector cleaned for you and to some people, this is a small price to pay if they do not have the time and do not want the hassle.

You could also remove the fuel injector and then clean it.

However, the equipment involved in doing so could cost you more money than you have or more money than you want to spend (thousands of dollars).

Therefore, the professional cleaning service is usually the best way to go unless you buy the $100 cleaning kit. It’s up to you.

Some people like the peace of mind of having someone who knows what they are doing handling this task. However, if you know a little bit about cars you probably could handle cleaning your own vehicle’s injector and/or gas line.
