blame that on ethanol fuel....
Could be. I drive for a living so I run it from F to E. Well twice I blew the O-ring out of the sensor at the top of the tank so any fuel in the neck leaked out. I was thinking it was the pressure every time I filled it up. Then I went through a fuel pump and the GM service tech actually told me it was heat build up because I frequently run it below half. He told me to KEEP 1/2 a tankit to cool the pump. CRAZY. BUT besides a front wheel bearing (and 2 sensors & 1 pump) the thing PURRED through 200k miles.
