When I swapped out my fuel pressure regulator I did not get the Bentley
spec.
I just did this 2 weeks ago with a new one from BD ($60+) in a sealed Bosch
box. My pressure disconnected was 39 w/old reg. and 38 with new. No real
difference.
Connected was also 1# difference. 33 connected with 11" vac or something
like that. The new regulator did not give me what Bentley specifies,
connected or not.
I used a test gauge that was calibrated by the instrument techs at the large
factory I work at.
Listee Mark Keller is happy with his 'CB Performance' adjustable regulator.
