Oldsmobile/Buick Repair: Vacuum line, vacuum diagram, vacuum line

Question
I need a vacuum diagram for a 97 Olds 88. The line runs from the regulator on the fuel rail to somewhere else (this is what I can not find). ther is gas leaking out of this.

Answer
Hi
The vcuum line for the fuel presure regulator runs from regulator to large port on throttle body. That large port has 2 vac. lines, the other is for the EVAP purge solonoid, which is located same side as regulator, between the first 2 injectors.
If there is gas present is ANY of these lines, it HAS GOT to be repaired..
I hope this helps
