Hi
I would like to know the answer to the question as well. Wouldn't it slightly disturb the reading that the fuel pressure regulator gets?
regards,
Richard

That is a good location. With that location you will be able to verify that the regulator is seeing when the motor goes in boost. If your gauge is not showing any boost then you know you fuel regulator is not seeing it. If regulator does not see boost it does not increase fuel pressure thus leaning out the motor.
Remember to do a spark plug check after the first short burst to verify the engine is getting enough fuel. If you lean it out you will be rebuilding the motor.

Any vac line or port will work. I agree with Turbojack, that would give you a direct reading on your regulator.
Make sure you check the plugs after a hard run and then turn the key off while still underway. If you bring it down to idle and then shut it down, you'll be reading your idle mixture on the plugs.

Shouldn't the regulator be fed from vacum off the Carb box and the boost guage come from the Intake manifold. They will read differently.
