Wrongway,

 

There were a couple of internal changes in the injectors early on affecting the 2003 models. I cannot find any of the published info on this that used to be posted, so forgive me for any inaccuracies or perhaps somebody else can chime in.

 

Early 6.0L injectors had several problems:

 

• The first of which was fuel leaks from the BODY o-ring, which is an internal seal, that was corrected - likely with a new seal. (I don't know)
• There was a change to some clips on the top of the injector, spool valve pin I think. Looks like that is now configured more like a bolt and retained with a nut instead of clips.
• The intensifier piston was also changed, something about keeping the return piston centered. The return springs used to shift and cause uneven loading on the piston resulting in scuffing of the piston bore resulting in misfires.

I will research this a little more and revise this message as needed. Other than these items, I don't think there have been any major changes that have been published or announced.
