I have a hard time believing anything that Ford says when it regards a potential warranty issue. I have on numerous occasions fought (and won) with the Ford warranty department and their engineers about the fuel system on the 6.0 and 6.4 Powerstrokes. They are quick to point the finger at the consumer. I have paid for several outside tests that all backed my beliefs up. Once they were presented with the results, they ended up giving in. However with that being said, it is a business and they do need to stand their ground in order to keep a positive cash flow rolling in. If I paid the $60k or whatever those trucks cost, I would not be happy. I will look in one of the owner’s manuals and see if I can post more details on what the suggested uses of the Raptor are.
