Thanks will let you know when I get that done. For now I’m working on the fuel pump head. It was undated and there was no wear indicating failure per QS the plunger however did stay down on one side. It came back up with air or magnet but after depressing them multiple times one side continued to stay in. Will the rebuild plunger and barrel kit fix this or does this head need to be replaced completely?

The whole head shouldbe done.

Thanks I was digging around the forum and found a thread started by SquareOne where his torx head bolts were leaking. Now I understand the head a little better and why it has to be replaced.
