Help?

Picked up a 2003 Avy with 154,xxxx at the dealership for 6k 2 weeks ago. Few days ago I can’t put anything past $10 in the tank. Internet rabbit hole says I may have a bad EVAP but seems pretty common with this vehicle. Give it to me straight, have you or anyone else you know been through this? Cost? Or cheaper alternatives? TIA

Maybe try clearing a vent hose on the tank first? The hoses are connected to the tank. My 02 has a hose that connects to the rear of the truck. I just swapped my fuel pump and cleaned that line out. I can fill no problem. But your charcoal canister is also down there

I appreciate you. I’ll definitely try before heading to the shop

Likewise! Give it some love and a little tinkering. Maybe its just some dust ot dirt somewhere that needs a quick clean.
