Under the car just in front of the rear axle. It is connected to the main fuel pump. Both parts are hidden under a metal plate with 3 rubber grommets.
If you have the central injection system, you regulator is inside the plenum, next to the spider assembly. Takes about 20 minutes to get to it.
i In the gas tank attatched to the fuel pump. There is also a fuel pressure damper up in the engine on the fuel line as it goes into the injection system.
A fuel regulator is also more commonly known as a fuel pressure regulator. This component of the vehicle is located in the fuel tank and regulates the pressure placed on the tank as well as the flow of fuel through the vehicle's system.
what causes air injection system pressure to be stucked in cars
You will find the fuel pressure regulator under the upper intake manifold. The upper intake manifold will have to be removed to gain access. The regulator will be attached to the bank of injector poppets also known as the "spider".
it depends on the manufacter date. 5-3-99 had a fuel regulator with a fuel return, after 5-3-99, no fuel regulator, returnless fuel system. if it is flooding, look at the fuel pressure sensor bolted on before the injection rail, fuel line go's to it and has one vacuum line and one plug in.
Fuel Pressure Regulator is located on the fuel rail.Fuel Pressure Regulator 1. Disconnect the negative battery cable. 2. Properly relieve the fuel system pressure. 3. Remove the air cleaner outlet tube(s). 4. Remove any necessary components to access the pressure regulator. 5. Disconnect the vacuum hose from the pressure regulator. 6. Remove the pressure regulator attaching screws. 7. Remove the pressure regulator from the fuel rail. To Install 8. Discard the O-rings on the pressure regulator and replace them with new ones. 9. Lubricate the O-rings with clean engine oil. 10. Install the regulator into the fuel rail and tighten the retaining screws. 11. Connect the vacuum hose to the regulator. 12. Install any components removed to access the regulator. 13. Install the air cleaner outlet tube(s). 14. Connect the negative battery cable.

Purpose of a pressure regulator is to match the flow of gas through the regulator to the demand of gas placed upon the system. It is a valve that can automatically cut off the fluid of a liquid at a certain pressure.

It is a returnless system. When the fuel leaves the tank it is already at full pressure. The regulator is inside the fuel sending unit (inside the fuel tank, located under the back seat)
