2013 Dart SXT 2.0L 67,000 miles. When fueling car gas comes back up towards pump nozzle and shuts the pump off. I can only fuel for about 2 seconds at a time. I have tried various gas stations, holding the pump at different angles, etc. I took it into the dealer and they replaced two things: 1. Filter fuel vapor canister (part number 4627332ab) 2. Leak detect pump (part number 4861961ab). They said it was fixed and I drove off. I went to pump gas and the problem still existed. I took the car to another mechanic. He dropped the gas tank, inspected the area, and concluded that I had a venting issue. Made sense to me since the gas was coming back up to the gas pump when fueling. He said the gas pump (which is in the tank) is part of the venting system and that the pump would probably have to be replaced. He quoted about $300 on the part and roughly $200 on the labor. I told him to hold up because I wanted to see if I could work out a deal with the dealer first to see if I could get money back on labor that didn't fix the issue. Regardless, any thoughts on this? Has anyone experienced this before? Any help or suggestions would be greatly appreciated.
