Gas tank issues

I have a 1995 525i that I am having problems with the gas tank. About a year ago, the
gas tank deflated like a balloon and in turn broke the sending unit. The sending unit was
replaced a little over a year ago. About 1 week ago, the same thing happened again.
Aside from now replacing BOTH the sending unit and the tank my mechanic doesn't know
what could be causing that. Any ideas??????

You may want to check out your fuel vent system. I have read that if the vent tube is clogged (insects making a home), it will create a vacuum in the fuel tank and possibly crush it. Good luck.
