Check Fuel Fill Inlet – Ford [How to Fix]

Messages can be confusing to car owners, and one of the most common warnings that you will receive if you have a car is the “Check fuel fill inlet” which is going to appear on the dashboard of your vehicle. 

In today’s article, we are going to discuss what this message means, and we will guide you through the process of getting rid of it. 

Check Fuel Fill Inlet: Meaning 

This particular message means that your car has evaporative emissions, and they are leaking near the fuel tank. However, they could also be leaking directly at the fuel tank fill inlet. 

You will need to verify if the gas tank is fully closed, and that there are no leaks coming from the inlet’s pipe. This particular message can appear on the following vehicles:

  • Ford cars such as Fusion, Escape, and F150 trucks. 

You need to pay close attention to the “Check fuel fill inlet” when it shows up. Fuel fill is made of metal or plastic, so they are going to be vital to the car’s evaporative emissions, due to the fact that they can prevent fuel from leaking. 

What Can Cause A Fuel Fill Inlet?

The fuel fill inlet can happen due to damage to the fuel inlet, as well as a bad placement of a fuel cap. All of this can produce gas mileage and many EVAP system issues. 

A viable solution is to check the fuel fill inlet as well as the fuel tank. Make sure it’s fully closed. Next, if you have sealed it correctly, the engine light should activate the moment you start driving your vehicle for at least a mile. 

Another common scenario when this warning can show up is when there are foreign objects stuck in the inlet’s door, which causes it to not close appropriately. What you can do is clean the opening of the fuel inlet. 

Following this, you are going to have to reinstall the cap to make sure it’s done effectively. By doing this, there won’t be objects preventing the flap from closing all the way.  

Extra indications can be:

  • A missing fuel cap. 
  • A damaged fuel cap. 
  • Vacuum pressure leak. 
  • The screws on the fuel cap are too tight. 
  • Debris present in the fuel fill inlet. 

Advantages Of Checking The Fuel Fill Inlet

If you check the fuel fill inlet, you will notice if it’s sealed properly by the fuel cap. Also, you will prevent fumes and pollutants from being emitted out to the environment. 

After fixing the fuel cap to the fill inlet, a vacuum pressure seal will be created, and this will enable pressurized fuel to be able to flow correctly through the system. 

Moreover, thanks to a proper check of the fuel fill inlet, contaminants won’t enter the tank through small holes. Apply all of these solutions, and the warning should stop appearing on the dashboard of your truck or car.
