started getting really strong smell of fuel in the car when u put more than 3/4 tank of fuel and give it some stick. So I changed the rubber seal we’re the pump goes into the tank but yet this hasn’t fixed it. You can’t snell anything outside the car and there is no leaks in engine bay but smell is strongest in the boot which is still making me think the seal but can’t be as I have replaced this. Any ideas as need to get fixed fast as I am getting a headache on daily basis

 

how old is the car? :: could be the pipe leading from the filler cap to the tank
