I can't find the fuel pressure regulator on my 2003 Oldsmobile alero.
There are 2 fuel lines connecting to the fuel injector rail. The larger line is the pressure line and the smaller line is the return line. The smaller line attaches to the fuel pressure regulator. You will notice that the regulator also has a vacuum line attached to it. If you are planning on changing it your self, let me know. There is a specific way to change it for safety reasons.
Let me know.
Regards,
Below is a picture of the 4 and 6 cylinder fuel rails with regulators, not sure which engine you have. Each regulator is at the end of the fuel rail.
Hope this helps, let me know.
Regards,
is there a certain way to change it
Okay tell me how to change it if there's a certain way to change that pressure regulator
Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
Disconnect the fuel pressure regulator vacuum line.
Remove the fuel pressure regulator attaching screw.
Using a shop towel to catch any spilled fuel, lift and twist the fuel pressure regulator in order to remove the fuel pressure regulator from the fuel rail.
Remove the retainer and spacer bracket from the rail and discard.
Remove the fuel pressure regulator from the engine fuel return pipe.
Remove the fuel pressure regulator inlet O-ring and the fuel return pipe O-ring and discard. https://www.youtube.com/watch?v=EmIWBlc4...

I have checked both fuel lines that lead to the fuel bar and I see nothing like the regulator that I received from napa auto parts. A week ago I replaced my fuel pump and the fuel pump is working correctly, it is pushing out a three foot stream up on the fuel line when I take out the valve steam. There is nothing resembling the regulator I bought on either end of the engine. Exactly where is the location of the fuel pressure regulator on my car? Thanks for the help.
