mine failed at 35000 miles luck has it warranty took care of it. 100000mi warranty. when I baught truck. I have 55000 miles on it now. figure I probably have another 15000miles before it failes again. keep filters changed and keep records. it helps on the warranty process. have your pump pressure tested. some fuel pumps had low pressure causing cavitation of injcctor pump. make sure you also test it at running temp.
