The Fuel pressure Regulator is located between the carburetor and distributor. Mounting screw is beneath the retaining bracket leaving about 3 inches to work with.
* Remove distributor cap and rotor for access to retaining screw.
* Remove fuel line connected to regulator
* Remove rubber hose between throttle body and regulator
* Using a #30 Torx bit (1/4 socket type) remove retaining screw located beneath the regulator mounting bracket. Space is very limited so use of 1/4 inch breaker bar may be necessary.
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.
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.

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.
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.
