Hi, welcome to Justanswer.com my name is XXXXX XXXXX I will be answering your question.
If you have under 100,000 miles this repair is covered under the engine warranty. If not add about 40% to the warranty time for retail. You need to pull the cab off for this repair. The high pressure pump gasket is plastic and incorporates the wiring harness they are known to chafe.
Some 2008 F-Super Duty vehicles built prior to 8/20/2007 equipped with a 6.4L diesel engine may exhibit a lack of power or no start with possible DTC's P0003, P0004 and P0091 caused by circuit CBB12 at the high pressure pump gasket grounding to the high pressure pump body (may also result in fuse 74 being blown).
Follow the Service Procedure steps to correct the condition.
