RAM 2019 Classic (continued 4th Gen) - filler tube issue

[Eneto-55]

Here's the deal.  I cannot just stick the gasoline nozzle into the filler tube and lock it down - the gasoline backs up in there, and shuts the pump off, like the tank is full.  I had to hold the nozzle quite a ways up, and let it just very slowly fill the tank.  (I think I read something about this before, but I don't recall where.  Just bought gas a couple of days back, for the first time since we bought the pickup.) 

 

Is there a fix for this?  Install a larger diameter filler tube?  Is there something that has collapsed in there?

 

(I had been looking for a dedicated forum for the Ram pickups - thought I found one, but no one answers.  Anyone here ever heard of or experienced an issue like this?)

If it's a recent issue I'd guess the vent tube has become plugged or pinched.  If it's always been that way finding a different angle to hold the nozzle may help.  I've had several vehicles that would not accept stuffing the nozzle in full depth and locking the lever down fully and turning the nozzle sideways a bit helped.

 

It may or may not have a vent solenoid that is not working.  I have to assume it's a closed system for emission purposes.

First time filling it since we bought it, and judging from the other problem the car lot covered up (steering column flexible link dry, starting to seize), I doubt if they would admit that it was this way before they sold it.

 

How would I check for these different possible causes you mention?

If your state uses the gas fumes vacuum  when adding gas set up as Calif. does, if it not working properly the pressure will back up and cause issues like this.

 

Try putting a small amount of fuel in at another location?

 

Just a thought.

Thanks for your response.  This is a Marathon station near home, and I usually use this same exact pump when filling our other vehicles.  I have never had this issue with any vehicle I've ever owned, so I think that it must an issue with the tank or the filler tube.  Just had an idea - I think my son has a small camera he can stick in small opening like that, and he might be able to see if there are any obvious issues.  Will have to wait, though, as we just helped him move out of the house yesterday.  I can also try to see if I can see up in the side of the bed from underneath - maybe the filler tube is collapsed.  (I'm assuming that there will be a section that is rubber hose, but don't know until I try to look.)

I have had vehicles that just will not fill at certain stations. Specially a 2001 Astro that would not take gas from pumps at Thortons. Anywhere else was fine. No idea why.

Maybe the volume of the pump might vary enough to make a difference between pumps.  There's a ratchet in the handle for setting it at varous volumes.  I know we all like to go full bore, but will a pump fill the tank easier at a lower setting?.

No, unfortunately I couldn't even latch it at the first notch, and STILL had to hold the nozzle up, only part way in.  I could hear the sort of back wash.  Of course I suppose it's possible that they had changed that nozzle, or other settings at the pump.

I looked up in the quarter panel where the filler cap is, and I was really surprised how small that tube is (MUCH smaller than on my P15). I didn't see anything that appeared to be collapsed, but the rubber part could have an inside layer that might be separated from the outer layer, and be collapsed in there.  I'll need a camera on a stick in order to check that.

Thanks for all of the replies and ideas - possible causes to check for.
