We've seen the problem with the needle contacting the glass as Carl says. A few people have mentioned that. Adding something behind the rubber sealing ring to push the glass out is one way of solving this and maybe the easiest. Your sequence of assembly is right. I will always use a bit of red paint or a red permanent marker to mark the left connection points (please see image below). 12v switched ignition goes to "E" side of gauge and the sender wire from tank goes to "F" side of gauge.
