I started with the vapor vent valve and it got a little better. I did the rest as you did and it got a little better. Ultimately, pulling the tank and replacing the 11 year old fuel pump, sender, wiping all the pellets from the tank and blowing all the lines again cured the fueling issue.
All that occurred over a 6 Mo period and, thank God, I ran into the post about the carbon pellets or I would have been extorted by the dealership. That carbon canister kills 4-5 other parts. Thankfully the forum saves us the diagnostic costs.
It’s a pita to deal with but if you get all your OEM parts from RockAuto, use an Indi or DIY, your good for another 100k and you’ll have a gas gauge that is crazy accurate.
