The problem occurs because the diesel filler cap is not labeled nor is the filler door nor does the manual contain any notice. The cap on a 1997 vehicle (non-diesel fits on a diesel) one is apparaently vented one is not. But there is not way to as certain which is vented in which is not. The aftermarket dealers do not show a distinction. Apparently, the cap I placed on the vehicle was not vented and resulted in the tank imploding to the point that the intake tube and sensor were bent within 6 inches if the top of the tank. The tank was flattened. Gm needs to mark these filler caps. Dt.
