There is fuel leaking from above the fuel tank. This is an immediate hazard in my book. The tank is half full at this point in time. I believe it is leaking from the fuel pressure switching valve. No warning lights are illuminated at this time. I will confirm that this weekend when I remove the fuel tank to inspect. I have a photo of the leak but it is too large to upload. I will gladly email it to you. I am an ASE certified technician.
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.
