My first post,I have a 2009, 1500, 4x4 Silverado and have to change the drivers side leaf springs due to a broken center spring...it looks like the fuel tank is in the way of the front mount and of course the tank is full...other than that it looks to be a simple job and I will be doing it in a snow bank so what I really need to know is do I have to remove the fuel tank...thanks ,Ron
