I have a 2002 4 door civic and when braking on a downward slope I think I am hearing my gas slosh around. It is rather loud, and When I fill my gas tank up the sound stops. I was wondering if anyone else can confirm hearing the same thing in that year/model.

Doesnt sound like a good thing. This is the first time i've ever heard anything like this, at all. you might wanna get it checked out.
