6.0L Early High Pressure Oil System Seal Kit
fits 2003 - early 2004
(ONLY systems with aluminum high pressure oil pump and tubular oil rails)
It is advisable to purchase this Powerstroke HPOP seal kit when installing fuel injectors or a 6.0 high pressure oil pump.
We have seen many HPOP's wrongly blamed for starting issues resulting from leaks in the high pressure oil plumbing on early 6.0L's.
