IllustrationTHE MERCURY MOUNTAINEER WILL NO LONGER TAKE IN FUEL PROPERLY. CAN NOT PUT IN MORE THAN A HALF A GALLON OF GAS AT A TIME. TOOK IT TO A MECHANIC AND THEY SAID THERE WAS NOTHING BLOCKING THE GAS FROM ENTERING THE TANK. HE SAID IT WAS THE AUTOMATIC FUEL SHUT OFF THAT WAS INSTALLED IN THE VEHICLE. HAVE NOT REPLACED IT YET. *TR
