The two pressure regulators, can't remember the exact numbers but I think it's a 260 & 380 psi regulator, as well as the oriface for the timing relief I think.
I'll try and find it for you...

The pressure regulators are #'s 25 & 37. The oriface is under plug #59 I believe. He told me he uses a mirror & a pick for the oriface.

In service, under the IFSM drawing # 05c00201 shows it much less cluttered, but not numbered for a better reference.
