How much pressure is in a fuel return line?

When an engine is idling, it may be pulling 20 inHg of vacuum, which translates to roughly 10psi.

The reference to the regulator will allow it to adjust and lower the pressure in the rail to 48psi, resulting in 58psi effective pressure, which is the same as the base pressure.
