The Fuel Pressure Regulator is located on the fuel rail. The fuel rail located next to the engine valve cover. The fuel pressure regulator line needs to be de-pressurized prior to replacing the regulator. This may be accomplished by removing the fuse for the fuel pump while the engine is running. The engine will stop once fuel pressure is lowered.
O2 sensor/leaky injecters/fuel pressure regulator.
The fuel pressure regulator is located in the throttle body.
The fuel pressure regulator is located on the fuel rail right in front of the intake manifold.
on the fuel rail to the side
Stock base fuel pressure is 42 psi. This is the pressure when the vacuum hose is removed from the fuel pressure regulator. The vacuum hose must be plugged when its removed from the regulator.
Under the flux capacitor
It is in the throttle body.

To test the fuel pressure regulator on a 1992 Mercedes 190E, first, relieve the fuel system pressure by removing the fuel pump relay and running the engine until it stalls. Then, connect a fuel pressure gauge to the fuel rail's test port and turn the ignition to the "on" position without starting the engine to check the pressure. Compare the reading to the manufacturer's specifications; if it's outside the recommended range, the regulator may be faulty. Additionally, check for any fuel leaks around the regulator and ensure that the vacuum line attached to it is in good condition.
Release the pressure from the fuel system. Clean all nines and collectors. Remove the bolts that secureÊthe regulator to the engine and remove it. Use a new O-ring with the regulator. Install the new regulator. Re-pressurize the fuel system.
I don't know if your 1992 is the same as my 1995 , but looking from the front it is about 2 inches to the right of the oil fill cap on mine
i have a 1999 Dakota 3.9 and fuel regulator is on top of the fuel pump on the fuel tank... i have a 1999 Dakota 3.9 and fuel regulator is on top of the fuel pump on the fuel tank...
