OK,
I bought this 99' Mercury Grand Marquis from my inlaws and it was always like dragging (the rear end) only when I pulled out of a driveway. I assumed that it was similar to the plastic that is attached to the front of the car that makes a "scraping" sound when you pull to close in a parking lot and hit on one of those concrete thingys. I hope this make sense.
Anyway, yesterday,I went over a RR track

and this black box looking thing came lose and was dragging. Luckily I had some bungi cords and it is being held up right now (temporarily).
I don't know what it is exactly. Description:square box bolted to bottom of fuel tank, about 12" x 12" or so.. and it has 2 hoses coming off the side
and also has an electical type plug. The box broke lose and was dragging on the ground. Anybody know what this is??????????
I am a single mom, who does alot of stuff on my own. I need to call for help, but don't know what to call this thing. Help!! All serious answers appreciated.
