Replacing fuel pressure regulator

My '95 Aurora has problems starting when warm (starts fine first time of day, requires several long cranks otherwise) so I'm replacing the fuel pressure regulator.

I don't have a manual for this car, and was hoping some kind soul could give me some pointers...exact location of the FPR, how to depressurize system, and any other useful pointers before I get in there. Thanks.

auroraclubna.com, you're welcome

For anyone who is interested: this did fix the starting problem, and also fixed the bogging down/stalling problem we were having. Pretty good for a $41 cost!
