kevin phillips Posted July 19, 2007 Share Posted July 19, 2007 does anyone know when the oil pump (high pressure) changed from the original style like the 2003 6.0 powerstrokes had to the new style like on a 2006 and if a 03 could be modified to accept a new model pump thanks in advance for any help Quote Link to comment Share on other sites More sharing options...
WGLR13MWZ Posted July 20, 2007 Share Posted July 20, 2007 Assuming you are talking about an F-series 2003 - 2004 3C3Z-9A543-AARM Ser # 6,000,000 to 6,155,636 2004 4C3Z-9A543-AARM Ser # 6,155,637 to 6,344,942 2005 - 2007 5C4Z-9A543-B Ser # 6,344,943 and up Just in case E-series 2004 4C3Z-9A543-AARM Ser # prior to 151,888 2005 - 2007 5C4Z-9A543-B Ser # 151,889 and up As far as retrofitting, I do not know.

Keith Browning Posted July 20, 2007 Share Posted July 20, 2007 Interesting idea but why would you want to do that? I would think it would involve the pump, the branch tube, and possibly the supply tubes and oil rails if the parts don't fit as you go from the pump onward...

WGLR13MWZ Posted July 20, 2007 Share Posted July 20, 2007 Also as a side note. The original HPOP when remanufactured and sent back out for service parts are stronger and more durable. They bore out the cylinder and sleeve it with a different material. This dramatically reduces failures related to the cylinder becoming egg shaped which in case was one of the most common failures.
