so i had the car running today while i was washing it and i heard this wierd noise coming from the fuel cap. at first i thought it was b/c the subs were pumping but then i listened closer and heard it coming from the cap itself. i cut the stereo off and put my ear to it and it sounded like a gurgling noise. almost as if the cap was off but it was on right and tight. is this normal or does this have anything to do w/the overflow tube? it seriously sounds like somethings open and maybe this could have something to do w/the excessive fuel consumption im dealing with. now on a 2000 svt w/48k miles, im not sure where im at. ive replaced the fuel filter and run fuel injector cleaner in it every fill up for a month straight to clean it up. what else could it be? im really lost on that noise from the gas cap. any help would be great! thanks in advance
