Earlier in the thread there was a comment about "imploding" your tank.
That actually happened to me. Yonks and yonks ago, before I saw the light and the error of my ways, I had an MQ Patrooool. One of my bros and I were coming back from Fraser and unbeknownst to us the breather clogged with sand and jelly fish etc.
Before we realised the problem the fuel pump sucked the tank almost inside out :eek2:.
