On two occassions about 1 month apart the gas tank ruptured and poured gas on the ground under the vehicle, Gas tank looked like it had been hit and caved in but ruptured near a corner. First time figured I had hit something and caused it. After 2 weeks in the shop I had babied where and how I drove the truck but it did it again in the same way in the same place on the gas tank.Just before it pours out gas I heard a sound like a heliocopter hovering and felt some vibration, could have been the tank imploding but I don’t really know. What could be causing this?

Sounds like the fuel tank is collapsing under vacuum, the evaporative emissions system may not be venting properly.

Agreed there is a vacuum issue causing this. At one time VW had a problem with some cars suffering collapsed fuel tanks due to an evap emissons problem.  
Those tanks would really get flattened. Capacity was around 2.5 gallons total.

Spiders in the EVAP system can cause a gas tank to implode.

Look it up!

Until you’re sure this is fixed, you should probably open the gas cap every so many miles and listen for air being sucked in.

did the tank get repaired or replaced after the first time?  
just curious.

I agree with the others- evap system issue. is the Check Engine light on?
