Problems fueling

Just recently I have had problems fueling my 2004 2.7. I've always put the nozzle in the tank and set it on it's lowest setting until it clicks off and then I hang it up. Recently, I can't do that anymore. No matter what I do it clicks off unless I hold the nozzle part way into the tank at a very low setting by hand.

I originally thought it was just Chevron or some new law causing this but it is happening at every gas station I go to and I just had the problem in WY, UT, and NV. I normally buy non-deathanol in WY and since I just took an 1800 mile trip to NV and back this problem happened at every gas station I stopped at with every single one being Chevron except for one. I also had the same problem where I normally buy the Deathanol free although it doesn't happen every time.

Does anyone have a clue as to what is causing this? Do I have a bad valve or something in the emissions system as far as vapor recovery? The last thing I want to have to do this winter is stand out there and "baby" the pump in a 60 mph wind at 10 degrees this winter.

 

It is most likely that your charcoal canister is plugged up or a line going to or from it is. The problem: The gas tank is not venting while fueling. When the charcoal canister( scrubs the air leaving the tank of gas fumes) is plugged up, air can only escape through the fill neck which cause the fuel to to back up in the filler neck causing the automatic fuel cutoff at the gas pump to cutoff.

 

Wow, I had never thought about that. Thanks for sharing

 

Thank you very much for that information. I had been thinking about that charcoal filter for a while now and wondering if I should replace it. I'll check it out. Once I find it. Do the first gens have them under the truck near the fuel tank?

 

On my ‘03 V6 it is near the tank on the driver’s side. The black box with all the hoses plugged in to it.

Here's an update. I took the line off of what I think is the VSV valve under the hood that runs to the fuel tank. I blew compressed air through it and the problem is solved. I could hear the air coming out of the filler neck. It seems that the line that runs to the fuel tank can get clogged so blowing out fixed my problem. I'm still going to get under there one of these days and check out the canister. You can tell if they are going bad by pulling the hoses and checking for little charcoal pebbles in the hose.

 

Thanks.

 

Sorry for the post revive. I have the same issue. Can you please elaborate on how to identify the VSV valve under the hood?

 

Check this thread out. Lots of good info

one vents the vapor to the intake...

other one vents excessive pressure off the canister...
