high fuel pressure at idle

[QUIP'6']

working on a 84 olds with a gn drivetrain and put a fuel pressure gauge on it and to my surprise it is 64 psi line on and 71 line off. this is with a stock bosch on there. could there be a restriction in the return line? or did someone really cruck the regulator. he just bought the car and i am straightening up the hacked up transplant. with 13 psi it does go to 84 psi

Sounds like the return line either is blocked, or non existent.

I see it there. Running back I will try to clean it out. Thanks
