Sorry I know a gas tank doesn’t really fall in this category but I didn’t know where it falls.
I’m having great difficulty filling my gas tank. I can only trickle the gas in, otherwise the nozzle will kick out. It appears as if a vent tube is plugged and the only escape for the air is out the filler tube which in turn is pushing back on the incoming gas and kicks the nozzle out.
“Pat13” posted this same problem back in 2011 and he appeared to be the only person with this issue at the time, as no one had any suggestions for him. I’m hoping I’m not just the second person to experience this and that someone might have a suggestion for for me.
thank You !!

 

My son's Sentra had the same problem, I had to replace the evap canister. I recall one forum member posted that their tank had collapsed, hopefully that's not your problem.

Thank You ! That only stands to reason. I’ve read things about over filling and that it can cause issues with the evaporator, which I suppose is the only vent you have. I don’t recall over filling but that doesn’t mean I didn’t. Hopefully it’s not to hard to access.
Plus side to a collapsed tank, would be the cheaper cost of a fill
thanks again !

 

There is a roll over valve at the bottom of the fill tube and it has been known to stick. There is an airspace above this valve, if the valve is stuck open this air space can be reduced and this probably causes the evap tank problem. If the valve sticks partially closed it would only let a small amount of fuel pass the valve and slow down the filling.
That is what I recall to be the cause of problems.
The collapsed tank happened when the pump kept pulling gas from the tank when the vent to air was clogged, the pump just kept pulling and the air pressure in the tank dropped too low causing the tank to collapse. I find this hard to believe but there was a thread on it at years ago.
