I have seen numerous posts about damage to the fuel sending unit from pump nozzles. Here in Kansas the nozzles have a large spring assembly on them which prevents it from entering the tank more than a couple of inches. I can't imagine someone here being able to get close to the sending unit tube. So you guys that have experienced problems, are the nozzles missing the spring assembly or is something different with the vapor recovery nozzles which we don't have here (yet)? Just wondering what causes the dents.
