IMPOSSIBLE TO PUT GAS IN MY BRAND NEW 2021 MACH 1 - NEED HELP

[Epiphany]

Can you please get a better photo of the plug? Maybe hold the flap open with a pen, etc and get a shot deeper into the cavity?

so is the "rollover flap" the outer or inner flap (if the lower one is indeed a flap)?
The lower one doesn't t look like a flap but more like a cap. As some already suggested.
Does the lower flap open with a long thin screwdriver? If not it s a cap or broken flap I d guess. Got to get a better look at it to see which it is.
I bet there is a simple answer that Ford performance can find for you.

OK, so found this.

So exactly what does “Wo/Inhibitor” mean?

If you can't remove that restrictor ring without removing the filler neck I suspect that you'll need to have the filler neck replaced by the Ford Dealer. In the meantime you'll need to use a portable gas can to fill the car. You might be able to use the little white plastic funnel in the trunk well but I think it will also make a mess. I use a long funnel like the one below when filling the car from a portable gas can. (It's part of my hurricane kit for the car.) It fits easily in the opening in the filler neck and allows me to pour gasoline without worrying about splashes and spills.

Hope you get it sorted out.

We might be getting closer to an answer. Checkout these two videos.



There may be two clips that need to be released to allow the internal cap to open. The F150 video shows what happened when the wrong nozzle is used.

My initial thought is "wide open inhibitor", but I am still researching.

It does not explain the difference in size.

Several made the comment the factory might have put the wrong inhibitor for the Brazilian market on this car.

What I find interesting in the F150 video is that the same station has pumps with two differential nozzles. One works, one doesn’t. I think this could very well be the issue.

two differential nozzles.

I really wish he could have panned up so we could see the pump. The insight is great, but I would have wanted to see the different types of fuel, if there were fuel type differences between the two pumps.

The other thing that interests me is the type of fuel used in Brazil. I was aware they refined fuels from sugar cane and it's Ethanol. I'm not sure how that impacts this specific problem. I mean, before, previous models, it was not an issue. IDK...

with this in mind have you tried another pump and/or another station?

I did open it with a screwdriver

The internal deep lower flap does open
Hard to get an image, though
Very very narrow

Here there is only one diameter nozzle

Well, my other GT's do not have that issue, nor does an used 2021 Mach 1 for sale at the dealership

Excellent videos
Yes, I did try some other gas stations; same situation
Gas pump nozzles are the same everywhere

 

[cerbomark]

so the lower flap opens but the nozzle doesn't fit.
If that is certain then it s a different flap than used in your country.
Order the correct unit and test it at the pumps before you install it.
So we are assuming the flaps are different for different locations? That s what you need to ask Ford.
Maybe that second flap came in at a certain Vin# as something new ?
