Uni,

Is there a serial break to confirm this or is this simply a fuel pump upgrade when replacing the parts? The serial number for my engine is 799033XX.

Not that I want to stretch the replacement of the parts as mine is at 270k now, just would like to know to satisfy my own curiosity.


BTW, I was reading the back of my butter container and noticed a very familiar image...lol

there isnt a serial number break unless your engine build date is fairly new (2017 or newer). You can tell the old tappets and rollers from the new ones by the side play of the roller pin. In the old ones the roller pin had keepers to keep the pin in the roller. The new DLC ones free float and have no keepers to keep the pin centered. You can push them in and out freely.
