How do you replace the high pressure oil pump on a 6.0L Ford F-350?

Answer 1

It depends on the year. For 2003 and early 2004 models with the cast iron pump cover with aluminum pump go ahead and remove the entire intake to gain access to the pump. For mid 2004 to 2007 models with the aluminum pump cover with the cast iron pump only the turbo,pedistual, and loosening of the y-pipes is necessary. Two of the pump cover bolts under the egr cooler are a little tricky and take caution that the bolts do not fall into the engine this may happen because of the way you need to twist the cover out. Using some trans gel on them helps keep them in place when re-installing the cover. It is common for the 2003-early 2004 aluminum pumps to fail but the mid 2004-2007 cast iron pumps are pretty much bullet proof and don't fail often other then the STC fitting blowing off causing a crank no start issue. Their is an update fitting available to fix this problem. If the fitting blows off hard enough it can and will crack the rear cover causing an oil leak at rear of engine and also bends the branch tube soo bad it is un-useable!! If this happens the easiest way to replace this critical tube is to remove the engine, both heads, rear cover, camshaft lifters and a bunch of other components to gain access.
