I had this problem with an old VW pickup truck. Excessive vacuum caused
the bottom to suck up and cracked the sides where some internal fuel
injection distribution ports ended. Bottom line was that I could never get
that tank to stop leaking (but at least it was below the body, not inside).
I would try to find another tank.
