Fuel pressure?

what is the stock fuel pressure on a b18b1?

40-47 psi.

thanx, have a motor but had no fuel rail on it an i had an adjustable fuel press. reg. with aem fuel rail layin around so i figured i would use that jus needed to know what press. to set it at.

That 40-47 psi on the stock set up is when the vacuum hose is disconnected from the fuel regulator. When the vacuum hose is attached on the regulator fuel pressure should be between 31-36 psi. You probably shouldn't have a problem though.
