Fuel fill inlet light is on in my 2014 Mustang. It’s NOT a gas cap issue because this model does not require or use a gas cap. Can this possibly be catalytic convertor issue? Mechanic's Assistant: Just to clarify, what are the exact lights you're talking about? Fuel fill inlet Mechanic's Assistant: What is the make/model of your '14 car? Ford Mustang Mechanic's Assistant: Are you fixing your Mustang yourself? What have you tried so far? Yes. Did nothing so far

Hi Ronnie. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Ronnie, do you also have a Check [Engine](/topics-engine-ford/) Light set?

Automotive Expert
Ok, great. Thank-you, Ronnie. Please give me one moment to type out some information for you. Sit tight one minute... I'll be right back!

Automotive Expert
Thanks for holding, Ronnie. From what you are describing here, this sounds like it will be the case of a problem in the EVAP (emissions control/recovery) System. This warning sets when the on-board computer sees the system is not holding pressure. And it assumes the reason is the problem is the inlet not sealing correctly, resulting in a leak. This will not be the case of a failing Converter. First thing to do here is to use a funnel and open and close the 'flap' located at the top of the fuel filler neck (where you put the fuel dispenser nozzle). Move this flap a few times and make sure it is sealing correctly. If this does not solve the problem, then the next course of action is to have the EVAP system "smoked". This is where a machine forces smoke through the system and any leaks can then be more easily found and repaired.

Can resetting the flap itself possibly fix the issue?
Automotive Expert
Yes. That's why I suggested doing that first.

Great. The vehicle is not with my now, but I'll try that ASAP.
Automotive Expert
Sounds like a good plan, Ronnie! Glad I could be of some help today! I hope everything works out well for you! Have a great day! Thank you for choosing Just Answer for your questions!

Question: it needs gas. Could my simply putting the gas nozzle in several times correct the issue?
Automotive Expert
It 'can' but you really don't want to be banging the metal dispenser nozzle against the inlet. It'd be a lot safer to use something plastic, like a funnel, as I mentioned above.

Good deal. Thanks & Merry Christmas ��
