E250 fuel filling problem
Like many others, I am having serious problems filling the fuel tank with my 2004 e250. Every time I try to pump gas into the tank, the trigger is switched off because the sensor in the fuel nozzle is tripped by either fumes or fuel backing up the filler neck. From what I've read it's probably an old, clogged charcoal EVAP canister, or a clogged antisiphon mesh (or whatever is employed for antisiphon). I've spent a while looking around under the truck for the charcoal EVAP canister but cannot find it. Searched the internet for a picture or diagram so I could get an idea of where it's located, but still no luck. So now I am here, asking for help from the pros. I appreciate any suggestions you may give me.
Also, if it isn't the EVAP canister or antisiphon system, any other ideas of how the fuel is being prevented from freely flowing into the tank? This problem is ridiculous. At times it takes 15 minutes to fill the tank with five gallons.
I have searched and found several helpful threads regarding this issue, but none including a picture where I can find this EVAP canister so I can inspect it to decide whether or not it's the culprit, and either delete it, clean it out, or replace it. Thanks in advance!

If the ignition and/or engine is off during refueling there would only be physical issues causing your problems. Most who've had this same condition find out the vent tube running along side the fuel filler hose/neck is clogged.
I'd first begin by making sure the physical passages are clear and unobstructed.
Your EVAP canister will be just behind the rear axle with at least one soft flexible tube and an electrical wiring harness running to it. If you still can't find it let me know and later today I'll crawl under my E250 and snap a photo.

Correct. I don't know exactly what it does or how it works but I believe its nothing more than a purge valve of sorts re-introducing fuel vapors into the system at some point. (Don't take that as anything technical---just a hunch on my part.)
This same situation has been discussed here before and nearly every time its centered around the filler hose and vent tube.
