I have a 92 Ford Escort GT. When I fuel up, I smell raw fuel vapors in the interior of the car for one or more days afterwards. It seems to be strongest in the front portion of the interior. I suspected the fuel tank/pump cover under the rear seat, but it is not as strong in that location. I can find no leaks underneath. I have checked all the lines and the injector sockets. I have looked for small leaks near the firewall. Nothing. If anyone has had this problem and found the source, I could use your help. Thanks. It´s been a while since I posted. It took a while to figure out the revised site.
