There has been this awful smell coming from the car. First, I thought it was from the little presents that mice and other critters can leave over almost a half century of calling something home. Today, while messing around with the trunk wiring, I leaned down into the fuel level sening unit and pushed my finger through the top of the gas tank. Such a stink arose. You can see what I found when I cut out the sending unit. Later when I could not stand the smell any more, I cut the top of the tank open. There was about two gallons of what used to be gas, and about two gallons of rust sludge and stink.
