It would seem the no good low life who did all the gouging with a key or whatever on the hood and front fenders of my pickup last summer also decided to "add" a little something to my gas tank! Haven't drained it yet, but just taking a whiff through the filler car it kind of smells oily??? Maybe some dirty oil, or possibly diesel fuel? Oh well, I guess I needed to drain and flush the (brand new 1 1/2 years ago) gas tank anyway!!!!!
