I own a 2004 GMC with 33k miles.
Last night my designated pumped gasoline in my Duramax.
Gas gauge was in the RED and pumped $20 of unleaded gas.
My truck quit after driving about 10 miles up a montain road.
How much "long term" damage might this have caused ?
Do I dare take it to GMC dealer to drain gas and purge fuel lines
since they might VOID my extended warranty ?
Thanks
