ENGINE AND ENGINE COOLING

I BOUGHT THIS VEHICLE USED WITH ABOUT 66,000 MILES ON THE ODOMETER. SHORTLY THEREAFTER, THE CHECK ENGINE LIGHT CAME ON, AND I FOUND AN EVAPORATIVE EMISSIONS CODE STORED. I CLEARED THE CODE AND WENT ABOUT MY BUSINESS. NOT LONG AFTER, I WENT TO FILL THE TRUCK WITH FUEL AND GASOLINE SPILLED OUT FROM THE TOP OF THE GAS TANK WITHOUT COMING UP THE FILLING NECK. WHEN I GOT AROUND TO TAKING THE TANK OFF THE TRUNK TO LOOK FOR THE CAUSE OF THE ISSUE, I FOUND THAT THE TOP PLATE OF THE FUEL SENDING UNIT HAD RUSTED THROUGH AND LEFT AN APPROXIMATE 1" X 1/2" HOLE WHERE FUEL AND VAPOR WAS ABLE TO ESCAPE. AS FAR AS I KNOW, THIS WAS THE ORIGINAL SENDING UNIT FOR THE VEHICLE. I AM REPLACING THE UNIT WITH A DELPHI SENDING UNIT WITH A PLASTIC TOP; HOPING THAT THIS WILL PREVENT FUTURE LEAKS OF THIS NATURE.
