Once i begin driving usually on the highway i begin to smell a fuel smell. as if my car was leaking gas. i brought it to 3 different mechanics and they all notice the smell but cant figure out where the leak it. they have looked everywhere. if anyone has some insight on this matter please help me. thanks
i've looked over all the fuel lines. not one is rotted or broken. fuel pump would cause a smell?
