What is Fuel Fill inlet?

As the name suggests, the fuel inlet is the hole through which fuel is poured. While most models come with a traditional fuel cap, some newer models feature a cap less fuel tank.

While the name may be to at least some people, most of us will be familiar with the location of the fuel tank. In the other words, the cap is located on the outside, usually behind the fuel door, leading to the fuel tank.

It has feature such as an internal value or check value that present fuel vapors from escaping. Therefore, the condition of your fuel filler is definitely crucial in maintaining the efficiency of your cars fuel system.

What does check your fuel fill inlet mean?

How to Check Fuel Fill inlet

The check fuel tank warning sign is a concern on many Ford vehicles, including Mustang, Fashion, F150, Explorer and More.

What Are the Possible Causes of Check Fuel Fill Inlet?

Here are some causes for check fuel Fill inlet.

1. Loose fuel cap

A loose or missing gas cap is the most common cause of the fuel tank light coming on. Your gas cap is an essential part of your evaporative emissions system, (EVAP) and for good reason.

First the gas cap prevents fuel from leaking and prevents dirt or debris from entering the fuel bank.

When the cap is properly secured to the inlet, it the creates a vacuum seal, allowing pressurized fuel to flow smoothly through the system.

In addition, the tank cap ensures that dangerous gases and pollutants are retained in the tank and cannot escape into the environment.

The fuel cap also captures fuel vapors that would otherwise be released into the atmosphere, allowing them to be reused in the car.

Therefore, if the cap is not properly tightened or damaged, gas leaks and reduced fuel consumption may occur.

2. Over tightening 

If you overtighten the tank cap, you risk damaging the rubber seals and cussing gases in the tank to escape though the tank cape.

This also causes the instrument cluster to check weather there is an error message regarding the fuel filling process.

3. Dirt and Debris

Dirt is also a major culprit When checking fuel gauges, especially on vehicles with capless gasket. Accumulated stains and debris become lodged between the spring-loaded cover and the walls casing (EVAP) leaks. Later

Models solved this problem installing a door at the start of the intake, but as a fuel filler door it is also susceptible to loss of tension and ingress of dirt.

To fix this problem, it is enough to clean the gasket and replace it with a new one if you notice any damage to the tank cap or tank inlet.

 Faulty Fuel Tank Pressure Sensor

The FTP sensor, as the name suggests, measures in gas pressures in the fuel system. This an important part of the Evaporative Emission Control (EVAP) system.

Here’s how to determine If a leak in the fuel system is due to evaporation.

This can result in engine stalling, poor acceleration, poor fuel economy and difficulty starting. The solution to this problem to call a certified mechanic to

Diagnose and repair the problem.

3. Use a Diagnostics Tool

If your fuel tank and gas tank cap are in good condition, the only way to diagnose the problem is to use an OBD11 diagnostic scanner.

This tool diagnoses your vehicle and retrieves stored trouble codes for your car. For example, if you have a PO457 code, this indicates a fault in the EVAP system. You can also consult your cars owner’s manual.
