At the outlet of the hose connection, or in other words, at the beginning of the hose. Be sure to include the hose valve in the hydraulics!

(63.5-mm) hose connection and 65 psi (4.5 bar) at the outlet of the hydraulically most remote 11/2-in. (38.1-mm) hose station. 65 psi is required at the end of the 100 foot long 1 1/2" hose or at the beginning? I would say at the beginning as that would be the outlet of the hose stations. But would like other opinions.
