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.
The High Pressure oil line disconnect tube (see related items below) is very helpful for disconnecting the quick-connectors (STC Fittings) at the HPOP discharge tube and and high pressure oil rails when installing these seals.
