Airtex 8012S fuel pump vs Mallory 4070LP

Two questions:

1. WHere exactly is the best place to measure the fuel pressure at the car? On the fuel line that goes to the rear carb or between the fuel filter before the gas gets through the fuel rail?

2. Which of this two pumps can dial approximately between 3.5 to 4 psi and less noisy:

or

Mallory 4070LP

For the airtex 8012s, i guess i will need a fuel pressure regulator. Not sure yet!
