The moral to the story is DO NOT TOP OFF YOUR TANK or you could (probably will) pay the price.The same filler neck vent tube hose connects to the gas tank at the same place as the fuel tanks Roll Over Valve
Right next to that vent tube at the roll over valve is a another vapor hose that leads to the charcoal canister.
IF you over fill the gas tank, ( topping off the tank ), the liquid gas has to go some where, so it travels out into the 2nd hose & goes directly into the charcoal canister & soaks the charcoal, therefore breaking the charcoal down.
Once the charcoal begins to break down, a signal is sent to the CPU & the CPU starts making several adjustments to the air fuel ratio as well as other things. The adjustments usually don't work & the is engine shut down & you get a no start condition
Sorry for the lengthy explanation, but i hope that i have given some insight to how the system works :4-dontknow:
same problemI have had both the sloshing out problem and within the last month it is hard to fill my 08 ram. Got a letter from Chrysler saying they had extended the warranty for this issue. Took my truck in last week and they replaced the filler tube and the check valve. I went to fill and the same thing but so sloshing out. Took it back today and they ordered the parts again to replace in case they got defective parts. They tell me that if this does not fix the problem, it could be the fuel pump going bad. Sound reasonable to any of you?
It's the rollover valve that gets stuck closed preventing air from escaping and not allowing anything to come in. Think of trying to put fill a water bottle with a garden hose attached. Unfortunately the valve is built in to the tank. I tap on the top if the tank to release it. Some have used WD-40 through the vent tube and others have drilled a hole in the tank and installed a fitting and hose to allow the air to escape. If these are no option than you need a new tank.ani solution !
I had the same issue with it taken a while to fill up and shutting off. They have fixed that issue but now like you say if overflows like a cup full. Yes would love to know how to fix this issueI have the opposite of this issue on my 2011... it won't shut off right away and spits about a cup of gas out and down the truck.
I appreciate all of the information and have started trouble shooting this issue on my 2004 Ram 1500. The snag is that I have not found any parts in the fuel or emission system called a "vapor recirculation tube." Can someone help me translate this to the term used in parts list?I had an issue with the fuel tank on my 2007 Dodge Ram 1500 not wanting to take on fuel, it took over 30-45 minutes to fill up from empty every time...and I put up with it for a year! Well I finally fixed it using the guidance below. If anyone else is having this issue, hopefully you will also find it helpful.

NOTE: This bulletin applies to all vehicles equipped with a gasoline engine.
Customer may report that the vehicle is hard to fill with fuel or that the [COLOR=blue ! important][COLOR=blue ! important]fuel pump[/COLOR][/COLOR] nozzle
shuts off repeatedly while trying to fill vehicle.
This customer complaint can occur due to a number of different causes. The fuel tank is
the least likely cause of this condition. The following Diagnostic procedure can be used to
diagnose the issues.
1. Is the vehicle a LX/LE/LC/L2?
a. Yes >> proceed to Step #2
b. No >> proceed to Step #4
2. Idle the vehicle 60 to 90 seconds upon stopping.
3. Does tank refill properly?
a. No >> proceed to Step #4
b. Yes >> Inform the customer to idle the vehicle for 60 to 90 seconds upon stopping if
vehicle was driven aggressively. This is due to the fact that on the LX/LE/LC/L2 the
fuel tank is a unique saddle tank design and needs 30 to 60 seconds while the
engine is running to level the fuel in both half's of the fuel tank. Allowing the vehicle
to idle for this amount of time will let the fuel pump transfer fuel to the left side tank,
opening the control valve and allowing normal fuel filling.
4. Disconnect the vapor recirculation tube at the fuel tank.
5. Attempt to refill fuel tank.
6. Does tank refill properly?
a. Yes >> Proceed to Step #7
b. No>> Proceed to Step #11.
7. Reconnect the vapor recirculation tube at the fuel tank.
8. Disconnect the other end of the vapor recirculation tube at the fuel filler tube.
9. Attempt to refill fuel tank.
10. Does tank refill properly?
a. Yes >> Replace fuel filler tube.
b. No >> Replace the vapor recirculation tube.
11. Disconnect the control valve to EVAP canister tube at the fuel tank.

12. Reconnect the vapor recirculation tube at the fuel tank.
13. Does tank refill properly?
a. No >> Replace Fuel Tank.
b. Yes >> Proceed to Step #14.
14. Reconnect the control valve to EVAP canister tube at the fuel tank.
15. Disconnect the control valve to EVAP canister tube at the EVAP canister.
16. Attempt to refill fuel tank.
17. Does tank refill properly?
a. Yes >> Blockage is in the EVAP Canister, or ESIM, or Clean air hose (ESIM vent
hose), or filter. Diagnose appropriately.
b. No >> Replace the control valve to EVAP canister tube.
