Randy,

Here is the whole document.

Here is my 2c on the oil pump check.
I had 2 oil pressure misses over the years on a newly assembled engine. This
is why I never run an engine unless it produces oil pressure with the
starter motor only, and plugs out.
The first time was a missed tightening of the pickup tube nuts, and the
second time was a missing outer rotor in the oil pump.
Both were really stupid errors, and off course not easy to admit.
All the oil pumps I ever used were old, and some really worn out. The worn
oil pump will first show up in low oil pressure.

On other thing, just for the records. The oil system diagram seems to be for
a 2nd GEN 13B. 12A's never had 4 OMP lines.

FWIW

Could be it came out of the 1st gen shop manual but they put 13B's in late models.
