You noticed something hanging from the rear wheel well on the driver's side of your 2014 Tundra. When you inspected it, you found that the rear fuel tank strap had rusted through and come loose from the frame, causing part of the fuel tank to rest on the skid plate below it. This happened at around 103,000 miles. The fuel tank strap will need to be replaced and inspected for any damage to the tank itself.

GOT A PRETTY MAJOR FUEL LEAK LEAKING OUT OF LEFT SIDE BEHIND DRIVERS DOOR COMING OUT OF THE FRAME RAIL. HAS AROUND 120,000 MILES. TOOK IT TO THE DEALER AND THEY SAID IT'S THE FUEL PUMP COMPUTER, NO WARRANTY OR TSB. SEEMS LIKE THIS SHOULD BE WARRANTABLE BECAUSE IT'S SAFETY RELATED. TRUCK COULD HAVE CAUGHT FIRE IF SOMEBODY FLIPPED A CIGARETTE UNDER IT IN TRAFFIC. IT'S A STEADY DRIP ABOUT ONE DRIP PER SECOND WHILE THE TRUCK IS RUNNING. AFTER YOU SHUT IT OFF, THE LEAK STOPS AFTER A COUPLE MINUTES AS IT DEPRESSURIZES. *TR

I WAS CARRYING AN OLD BATTERY ON THE TRUCK BED AND THE BATTERY LEAKS SO THE FLUID SPILLED OVER MY FUEL TANK AND BURN/CORRODE THE VACUUM AND GAS LINES. I THINK THE FUEL TANK SHOULD BE PROTECTED WITH AN UPPER SKILL PLATE BECAUSE IS A TRUCK AND YOU ALWAYS CARRY DIFFERENT THINGS AND THIS IS KIND OF EXPOSE OR DRAIN HOLES OF THE BED ARE NOT LOCATED PROPERLY, SO THEY WANNA CHARGE ME 2K DLS FOR SOMETHING THAT IS A BAD DESIGN PROBLEM.
