What should fuel pressure be at?
Fuel pressure for most vehicles should stay in a 5- to 10-psi range.
What should EFI fuel pressure be?
Typical EFI bypass regulators run between 40-80 psi while most carbureted bypass regulators are adjustable from 4-10 psi. Keep in mind that since the pressure requirements of a carbureted application is lower that an EFI application the flow rate of your pump will be higher.
