Fuel problem

[Acurtis35]

I have a 19' ram 1500 and the past 2x i went to put gas and the nozzel clicks off after a couple gallons. Takes about 20 mins to just get a half tank. No warning lights on. Any suggestions???

Use your warranty
The dealership will likely end up replacing your gas tank filler neck
chances are that won't fix it
so they will order a new gas tank & you will need another vehicle to drive around for a few days
Chances are the new tank will fix that issue

Never top off your Gas tank after the first click, that is what usually causes a valve inside of the tank to shut off
I think the valve is called a roll over valve, but i am not a mechanic

Your problem happens so often, that there must be a way to reset that valve, just my personal opinion

I learned to just put it on the first click, not wide open. Had to do it on the Durango and the Charger.

 

[Acurtis35]

I barely pull the trigger on the nozzel and after a gallon or two it shuts down....cantbuse warranty bc im past my warranty mileage.

There should be a vent line somewhere for the tank. Check to be sure it is not plugged up.

Have you had any work done to your Truck in or near the filler neck? If so they might have pinched the hose. Crawl under the truck and look to see if you can see if the hose is pinched. If not more than likely it will be the roll over valve in the gas tank is bad.

I have this issue only at certain gas stations/pumps. I learned that if u don’t stick the nozzle all the way in I don’t have this issue

 

[Acurtis35]

No work done on my truck....crazy thing happend yesterday at the pump i was having the same issue and after about 5 times that the nozzel clicked off the 6th time it never clicked off soooo whatever was wrong with it the truck fixed itself lol .....we shall see how long it lasts tho

This is a common problem with the capless fuel necks on the 5th gens (gasoline engine). Lots of people have had issues with this. Some say topping off your tank can cause this to happen. I had a different issue on my 2020 Laramie. I could only fill the tank to 7/8th full. I did sometimes top off the tank on that truck for the first year I owned it. It had the 23 gallon tank so I wanted to fit as much as I could in there. I haven't done that on my new truck, and after 5 months of ownership I haven't had any issues fueling it.

It's unfortunate that it didn't happen until after your warranty expired. Replacing the fuel tank can be a little spendy.

Dude, I hate to hear that. I JUST sold a 2010 F150 that did that exact same thing to me for 11 years. There was nothing you could do to make it fill up. The last tank I put in it before driving to the Ram dealership the F150 stopped me 8 times before I could fill it. Maddening. I hope you find a fix, I never did.

Looks like I’m in the gas nozzle click click club. I have a 2005 4.7 auto crew cab. I just bought it with 220 k on it and installed a reman engine in it. Beautiful clean truck, but I have refueling problems. I have been studying this situation and I think I may have found two possible solutions.

First there is a tube that connects the front valve and rear vent valves on the top of the tank. I think that with the broken nipple,I have seen commonly shown on forums, that everyone wants to attempt a repair the broken nipple which has had good results with a lot of effort doing so. I have not dropped my tank yet and I am researching all options of repair and preventive maintenance to correct future problems before they occur.

The air relief valves on top of the tank are connected by a piece of tubing. The front valve is where the broken nipple usually occurs from my research. It also seams that both the front and rear valves are linked by a lack plastic line and that by cutting that line and placing a tee fitting between them will suffice for venting purposes. Then put a screw into the broken orifice or dab some epoxy over it. Seems a whole lot simpler to me.

I’m also installing a new fuel pump assembly while I’m into the tank and I will wash it out with tank cleaner, install a new fuel pump and another rollover valve from an outside source that will install at a high point in the top of the tank for an auxiliary vent source if ever needed. There are multiple inexpensive universal sources available on eBay that include a rollover safety device and a compression attachment by simply drilling a hole in the plastic tank. Two of the auxiliary valves would be a great addition to the system IMHO

I have researched this extensively and have not found good source of the fuel venting system and canister trouble shooting available. Dodge has not given us a lot of support and having to replace an entire fuel tank at the price they want over a ball safety device is ridicules. I’m an old redneck and there are ways around the problem with a lot less involvement of time, effort and $$$

I will post an addendum to this post upon completion of my fuel venting address

Your solution is probably not going to work for those who have posted in this thread. This being a 5th gen forum, this thread is about those of us with the new (to gas 5th gens) capless fill neck, and the problems we are seeing with them. I don't want to discourage you from contributing, but I'm not sure what the two fuel systems (2005 vs 2019+) have in common as far as design goes. I would imagine much has changed in those 15 or so years.

 

[PROSOUTH]

I appreciate your information. I guess that with this ongoing problem of Mopar’s fueling issues it was so wide spread that I mistook this for the third Gen forum as I was searching for info on this site. The search function did not discern the proper forum under search. Thanks for your redirection.

You would think that in fifteen years Mopar would have finally gotten this corrected on all Gen’s. Thanx again. Jim

I don't think they have changed that much since 2009

Just like i don't think they changed the HVAC Box much, ( its under the dashboard ), since 2003

The fuel filler necks have changed a lot from 4th go 5th gens. The capless systems on the gas trucks are a lot different than what your ecodiesel has, and don't seem to like allowing fuel to pass unless conditions are perfect. I was also referring to the changes in the fuel nozzles themselves. EPA regulations are getting more strict. The auto shutoff function is more sensitive. All of this adds up to potential fueling issues at the pump. There actually have been a lot of changes since 2009. You're just not aware of them because of what you're driving. I never had a single issue with the 2015 ecodiesel I owned. And I haven't really read about anyone with an ecodiesel having issues with fueling.

 

[GTyankee]

IT is true, i don't know a lot about the capless Fill neck
My eco diesel has no cap, but it does have a flapper inside of the Fill neck.
I have had to insert a long screwdriver into the neck to open that flapper to retrieve a syphon hose.
my thinking is that they modified the anti syphon device to also seal off the system

I admit that i could be very mistaken.

I had a 2009 Ram 5.7L until early 2017

I do know about the issue with the straighter nozzle that almost every gas station had, up until when all the Costco Fuel pumps were changed over to the nozzle with the tighter curve in it & then many other gas stations also changed over to the curved nozzle.

When Chrysler/FCA started getting all these complaints about people not being able to fuel up normally, they started doing their due diligence.
It was actually a Ram owner that discovered the problem.

If you look at any fuel nozzle, almost at the end of it, you will notice a hole, it is small, maybe 3/8ths of an inch, That hole is the beginning of a mechanical pressure regulator.
What was happening was when they switched to the curved nozzle at the gas stations, it aligned that nozzle hole with the top of the vent tube opening inside of the fuel Fill Tube.

What Chrysler/FCA did was to change the position of the vent tube placement.

If you look at this image below, look for the placement of the vent tube





If they are still having issues filling the newest Rams
Possibly the fuel nozzles design has been changed again

As i typed this, the idea of if it can be done, rotating the nozzle in the fuel tube may help.
If that helps at all, maybe the Ram parts designers can move the vent tube hole around the Fill tube, like to the side or even the top of the fill tube

This is video that explains how the fuel nozzle works

Because my ecodiesel has the capless fuel fill neck, i can't put a cap on it.
So i did mod the fuel door

There are 3 possible issues that cause this:

1. Filler neck
2. Gas tank (rollover valve - which cannot be replaced separately)
3. Evaporator system (plugged charcoal canister)

The dealership will work through the list in that order unless they find something that points them to one in particular.

I had the same problem on mine (built 10/2018). There is a new filler neck design since my truck was built so that was replaced first. Fixed 90% of my issue for several months then the issue came back.

My tank was replaced and things have been great since. No more filling issues no matter where I go.

I've read of people needing new charcoal canisters to fix the problem. I'm not sure if that's a manufacturing defect as much as owner induced. The reason you aren't supposed to top off your tank is that air pocket you leave at the top is a buffer to prevent putting liquid (fuel) through the evaporator system which trashes your charcoal canister. That system is designed to scrub vapors, not liquid.

If you don't want to pay for a mechanic then it's up to your budget and skills if you don't want to live with it.

I had the same problem with my 2018 Ram 1500. I could only pump fuel pennies at a time. It took forever to pump gas. I took it to the Dealer and they replaced the filler tube (under warranty). Problem fixed …. for five months and then it ALL started again. My truck is BACK at the dealer and they called me this morning; I have a bad fuel pump that needs to be replaced. I’m still under warranty so I told them to fix it. We’ll see.

 

[Tonejer]

Same problem on my 19 ram... Have an appointment with the dealer for Tuesday...

 

[Tonejer]

I went to the dealer today... My ram already has the newer updated filler neck so they have to order me a new tank...
