dont listen to the gloom and doom, tsb's mean nothing they are a way to efficiently repair a condition if it comes up. there is no oasis on valves, fuel pumps , or glow plugs. there was oasis on egt sensors, the sync system and something else that are all covered under there own warenties. for what it is worth I have only heard about the fuel pump on the internet and I know no one who owns, or a mechanic that has ever seen one. not saying it isnt true but it isnt as prevelant as the internet has made out. I went from a 99 to a 14 and I stand by it was the best upgrade I have ever made in trucks, and I loved my 99.
