What is required to clean Fuel Injector?

You are required the following things to clean the fuel injector;

  • Choose any best fuel injector cleaner from our list above.

  • Hose in order to attachment to fuel injector and rail
  • U-tube

These are four things that are required to clean you fuel injector. However, make sure that you have all other stand by tools that you may require while working with fuel injector.

How to know that Fuel Injector is clogged?

There are few signs that you have to look for to judge that your fuel injector may be clogged. I have listed those signs below;

Lowered Fuel Economy

This is one of the apparent signals that your fuel injector may be clogged. If you have a digital meter then you may see the current MPG, do pay attention to it at least once per ride. If you are just travelling one route then measure the MPG on both side and compare. If you see a decrease in MPG then it is indicator of Poo fuel performance. However, lower fuel economy problems may be due to spark plug misfiring, bad air filters, incorrect tire air pressure, or any other such problems.

Problem with Engine Start

If you feel that you have to force your engine for some time after every start then it can be a problem with fuel injectors. Fuel injectors’ releases a mist of gasoline when one or more is not firing properly then it may give an unbalanced results. So don’t avoid this signal.

Not Firing on All Cylinders

You may have experienced this issue where not all of the cylinders are firing properly. You can easily hear it whether all cylinders are firing or some of them are working only. You may open your hood and if you see gasoline on the spark plug then you definitely have a clogged fuel injector.

How to Use a Fuel Injector Cleaner?

Now you might find this fuel injector cleaner guide pretty helpful as I have tried to write all the steps clearly for you;

Step one- Disconnect Fuel Pump

Firstly, you are supposed to disconnect the fuel pump from the fuel injectors. You need to use U-tube that will make sure that fuel returns back to the tank without wastage.

Step two- Disconnect the Pressure Regulator Vacuum line

Now you are supposed to disconnect the pressure regulator vacuum line that can be found slightly above the fuel injectors. Make sure that vacuum line remain intact upon removal and lean gently on the hood.

Step three- Connecting Hose to Fuel Pressure test Port

After that, you are supposed to connect the hose to fuel pressure test port and secure it tightly. Make sure that there is no exposure to any fuel of any kind and see that every part is clear. Fuel Injector cleaner is flammable so be very careful with this step.

Step four- Remove fuel tank Cap

You need to remove the fuel tank cap and store it where you don’t lose it.

Step five – Turn on the car

You need to turn your car on and make sure that fuel pump is off and then engage. Now the cleaner from your kit will begin to run through your engine. After 5 to 10 minutes, engine will shut down after cleaner has run its course then you need to remove cleaner tube.

Step 6- Reattaching

Now you are supposed to reattach the fuel pump power supply along with pressure regulator hose and then reapply your fuel cap.

Step 7 – Rechecking

Now start your car and see that fuel pump is connected properly and your car is functioning properly. Drive it for 5 to 10 minutes to check that everything is working fine. If you still facing the same problem then that mean your fuel injectors need to be replaced as they are already properly cleaned.

Alternative Method to use Fuel Injector Cleaner

If you are not comfortable with above method then you may use the below method that is pretty straightforward and easy.

  • You need to make sure that your tank is nearly empty. Also make sure that you have a gas tank spared.
