How to Use a Fuel Injector Cleaner in Seven Easy Steps

After reviewing the layout of your specific make and model engine in your user’s manual, you should get everything ready and prepare to get your hands dirty. It’s recommended to wear gloves during this to avoid gasoline/oil absorption through your skin.

1. Disconnection

Start by disconnecting the fuel pump from the fuel injectors. This will require you to use a U-tube to ensure that gasoline returns to the tank, or the fuel return line. Some vehicles will have a different way to go about this depending on your make and model.

2. Disconnect the Pressure Regulator Vacuum Line

Normally, this is found slightly above your fuel injectors, though it will vary depending on your make and model. Be careful to keep the vacuum line perfectly intact upon removal, and lean it gently over the side of the hood.

3. Connection

Use that hose you have sitting by; connect it to the fuel pressure test port, and secure it tightly. Ensure there is no exposure to fuel of any kind by revisiting these steps and ensuring all parts are clear. Fuel injector cleaner is flammable; use caution.

4. Remove Fuel Tank Cap

This is a simple portion of the process — just be certain to put it somewhere you won’t lose it.

5. Reconnection

Now, reattach the fuel pump power supply, as well as the pressure regulator hose, and then, reapply your fuel cap.

6. Quality Check

Turn your car back on to ensure the fuel injectors are reconnected and functioning properly. Drive it around the block for 5-15 minutes to really be certain. If you’re still noticing the same problems as before, and you know that your fuel injectors are clean as a whistle, you may need to replace them.
