I have a 2016 Ford Transit Connect XLT 2.5L Cargo Van. Ive been having fuel system issues with a P1450 Error codes which comes back as unable to bleed up fuel tank vacuum. I've changed the purge valve twice which resolved the issue for a while. now the error is back. Recently the car started fluttering occasionally and would shut off even though there was enough fuel in the vehicle. I've also heard a whining sound while driving from the gas cap area occasionally. I'm assuming the car needs a new fuel pump. Does this make sense and would you have any suggestions. Thanks Levi
