I have an early model year 2007 Tahoe with 110,000 miles. This truck was originally used in NH and probably saw 40,000 miles on NH salted highways in its first few years of use. Recently I noticed a smell of gas and within a couple days fuel was dripping from under the truck around the drivers side passenger door. This became a massive leak the next day spraying fuel all over. The fuel line failed at the outlet line of the fuel pump (top of tank where you cannot see it) due to rust and corrosion of the fuel line where it exists the top of the pump. See attched pictures.
I thought owners should be aware of this pending potential issue. I dropped the tank and replaced the pump and all is well again. When changing out the pump, be sure to purchase a new locking ring and swap the fuel level sensor over to the new pump. Also be sure to note the position of the sensor wires where they plug into the sensor, there are 3 holes and only two cables. One arrangement will not work. Don't learn the hard way as I did.
