The pressure is normally stated as 4-6 psi however there are absolute minimums......
Fuel: manual lift pump pressures.
Filter inlet min. ( lift pump to filter ) - 2.0 psi
Filter Outlet min. ( filter to injection pump ) - 1.0 psi
Most 6.9s-7.3s have at least 3 to 5 psi taken at the Schrader valve with core removed.
Volume is just as important, Specs are 1 pint in 30 seconds at 675rpms running or 1/3 pint after 10 seconds of cranking*** only, taken at the Schrader valve with the core removed.
*** FSS wire disconnected
