my car has been sitting for about 2 yrs now, i put in some sta bil about a year ago but im sure it was already too late. i dropped the tank yesterday and the inside is a little nasty. the gas was muddy looking and there are some particles inside, right at where the sending unit sits. im not too sure what it is, maybe rust. i tried to turn it over and get the gas out but because of the baffles its a little difficult. my questions are: a: how do i get the gas out? b: how do i clean it? or c: where can i take it to let someone do it for me? thanx in advance!
