One problem related to other fuel system pump has been reported for the 2007 Chevrolet Avalanche. The most recently reported issues are listed below.
The vehicle is equipped with the ability to handle flex fuel after you run the flex fuel then switch back to unleaded the fuel pump is damaged, I've spoken to other owners that own an Avalanche same model year and they are experiencing the same issue but gm ignores this. Can you offer any feed back for this ? if so thanks.
