290 - 340 kPa (2.9 - 3.4 kg/cm2, 41 - 48 psi)

B17A1 engine:

340 - 390 kPa (3.4 - 3.9 kg/cm2, 48 - 56 psi)

(with the regulator vacuum hose disconnected) 

2. Reconnect the vacuum hose to the pressure regulator.
3. Check that the fuel pressure rises when the vacuum hose from the regulator is disconnected again.
