I filled the fuel tank. Shortly I noticed that the fuel gauge level was rapidly dropping. I stopped the vehicle on the side of the interstate. Fuel was pouring from beneath the vehicle. A large puddle of fuel collected under the vehicle. I had the vehicle towed. The fuel pump had stuck at 65 psi and ruptured the fuel line. I had the fuel line and pump, along with the filter replaced.
