gas leak fill up

[NG_White30]

so i replaced my fuel pump just recently and doubt it has anything to do with this problem, but recently whenever i fill my car up with gas there is severe leaking out the bottom of the car, driver side, but then when i start the car and drive off the leaking stops....wwwtfff

Did you put a new o ring in when you installed the pump?

[NG_White30]

yup

Pull the rear seat and the access plate(s) for the pump/level sensors and fill the car. If they are the cause of the leak it wll be very obvious. If you have a 318 or early 325i/is/e/es with the 55l tank, you'll only have an access plate on the right side.
