According to www. the ranger station . com ( no spaces ) the oil pressure on a 2.9 L is 20 PSI @ warm idle and 55 PSI @ 2000 RPM
Key on, engine off......35 to 45 psi Idle with vacuum hose connected .....25 to 35 psi w/out .....35 to 45 psi
My Chilton book shows , for the 1995 VIN " X " engine ( 8th " character " of the VIN ) ( 35 to 45 PSI ) My Haynes book shows ( 39 to 40 PSI and 30 PSI at idle )
High or Low Engine Oil Pressure Check related links below
at idle 13-20 psi Key on engine off 23-31 psi
ford book says 65 PSI plus or minus 8
At idle should be 13-20 psi With key on engine off should be 23-31 psi
On a 1995 Ford 4.0 liter V6 engine : I believe that is 39/40 PSI ( 30 PSI at idle ) fuel pressure
