Allen plug under HPFP
Does anyone know what the Allen head plug is for that sits just below the high pressure fuel pump?

It's a fuel pump plug, for plugging the fuel pump. Oddly, new HPFPs come without them, assuming you move the old ones over; but, If you feel the need to replace them, you can! If you're replacing the HPFPs, I'd order them cause you'll likely find they're frozen.

And always replace these:

I don't really understand what this plug is for in relation to the hpfp? It's screwed into the head just below the high pressure fuel pump. So you would take it out of the head to plug the fuel pump for what purpose?
