Other Fuel System Hoses Lines/piping, And Fittings Problems of GMC Canyon

My 215 extended cab, long bed GMC Canyon slt has 13,000 miles and no accidents or hard driving (almost exclusively driven on the road) with some short hauling of loads locally (1500 lbs or less). No major work has been done to the engine or transmission. Today (9 oct 17), I was taking a short drive to home depot from my house (~6 mi), almost immediately I began to smell a strong odor of gasoline (travelled half a block). . . I had just driven the truck on Friday to work and smelled no odor, so I thought it must be a vehicle in front of me. But the odor persisted and was worst waiting at stoplights. I smelled gas again on the way back home and new it must be my truck. After I parked I popped the hood with the engine running and smelled no gas, upon returning to the cab to shut the engine off, I smelled strong gas again, and looked down under my truck and saw gas slowly dripping on the driveway. I shut the truck off and the gas continued to stream slowly down the side of the tank - it appears to be originating from the where the fuel lines connect to the in-tank fuel pump on top of the fuel tank. I could reach the top of the filler tube with my hand and it was dry, when I removed the fuel cap, there was no pressure so the fuel must be coming from the fuel feed line or the return line connections. After a few minutes with the engine off the leak stopped. The tank was not overflowing because it was only half full. I plan to have the vehicle towed to the dealer in st louis for repairs. I thought the lines might have been chewed by an animal (squirrel), but the lines are steel. I will find out more from the dealer once it is repaired.
