I stopped at a Chevron station yesterday to refuel my 2012 F150, which I've had since new, ran my
credit card, opened the fuel door, and tried to insert the nozzle. It wouldn't go it. I wiggled it, tried different angles and it just wouldn't go in (No it wasn't the
diesel unit). I looked at the tip, and saw no obvious problem.

I pushed on the flapper valve with my finger, then a metal rod, and it wouldn't open. So I assumed at this point the problem was with the truck.

A quick call to my Ford dealer got a service guy on the phone, even tho it was
Saturday morning. He never heard of such a problem, said you can't push the flapper
open with your finger, and said to try another
nozzle (Why didn't I think of that? Because I was locked on to the truck being the problem).

I went to the other side of the pump, brought that nozzle around; lo and behold it went in normally. I compared it to the first unit, and could see no difference at all. But there must have been some slight difference to make the first one
"out of tolerance."

I don't know how this flapper valve system works, but you can't just push it
with your finger or another object. Gotta be something the required size, like a
gas pump nozzle or the Ford filler funnel.

Anyone else experience this?

Here's a good informational video, although it's not the problem I had

 

Glad you brought this up. I always dump all of my lawn mower and generator gas into my vehicles in the fall and replace the same for the winter season for my genny.

I tried to open the filler tube with just any funnel and it ain't happenin'. You must use the Ford supplied funnel to open the neck, but, I've never heard of a gas pump nozzle not working.

 

Looks like there are tabs on the sides that have to be compressed to unlock the flap. If so, then the key characteristic would be the diameter of the filler nozzle.

 

Never mind....

 

Are you certain that there was no dirt behind the lock tabs of the trucks filler neck flapper? Even the smallest bit of dirt could be enough for the pump nozzle to not unlock the flapper. And the simply act of jiggling the nozzle around could have caused the dirt to fall out of place allowing the lock pins to slide inward unlocking the flapper. A little spray of wd-40 or some other sort of petroleum based lubricant can prevent this from happening.

After fueling the truck, I tried again to insert the bad nozzle. Still wouldn't fit.
The tip is probably slightly dinged up or out of round. I just couldn't see it.

I'm not real thrilled with this capless system. Or with a non locking
fuel panel door. Looks like what has been a less complex system in the past, with a gas cap, has
been over engineered.

 

You can buy a locking cap if you're concerned with security.

 

I would NOT use WD-40. That will just attract more dirt. Use a real lubricant like LSP1 or LPS2.

 

I have the capless system on both my 09 Explorer and my F-150. No problems with either so far (knock on wood). Having the Ford filler tube is a must if you want to use additives or need to fill from a gas can..

 

I only wish that Ford would have made that little funnel just a bit larger. It's almost useless.
