A few weeks ago, I suddenly started having issues when filling the gas tank. I had to hold the handle just enough to let it barely trickle in or it would back up and click off the nozzle. I've been putting about five gallons in at a time because just that takes about fifteen minutes. We'll be taking the ol' 'Hoe to Florida for Thanksgiving and I can't be having hour-long fuel stops. I ordered a new EVAP canister ("charcoal canister"), vent valve and adapter harness (new vent valve has updated design with a different harness connector). Yesterday evening I dropped the tank and removed the purge solenoid from the intake manifold to test it and to check the pipe coming to it. Although I have a lift, dropping the tank was a PITA since the axle doesn't droop very far due to the lowering components. I called it 'quits' for the night after smashing and cutting my finger when the tank fell.
New canister is identical to original- same part number, etc.:

These carbon pellets are supposed to stay inside the canister:

...But, they made it from the canister that is located just in front of the spare tire alllll the way to the purge valve solenoid on the intake manifold:

Tank completely free from the truck:

I don't know why these areas are that ugly brownish color. Even though it'll never bee seen, I still decided to wire brush and paint it:

Much better:

I didn't take many other pics, but I just used various nozzles on my blow guns to blast each pipe from both ends. I ended up removing all the pipes and hoses from the tank and blasting them while shaking and tapping them on the concrete. Those pellets were EVERYWHERE and stuck in there pretty good. I had to blast them from both ways to work the clogs back and forth until they broke free and blew out. I even removed the fuel pump assembly to clean out the bucket and the tank itself.
After I got it back together, I took it to the nearest gas station, an Exxon, and put half a tank of 93 in it. For the first time in a while, I was able to lock the handle at WOT and step away:

Holy ******* shit look at those pellets!!!!! Great work there my man!!!!!
...Three more successful WOT fill-ups so far with another happening today. I'd say this solution is confirmed.
