SOURCE: how to replace a fuel pressure regulator

Is it the 3400 v6 or the 2.2l four cylinder? If it the v6 then what you have to do is first know where it is. It located on the end of your fuel rail on the driver side of the car. There will be a plastic hose coming off the top of the regulator, unplug it. You then have to undo your fuel line that runs into the bottom of the regulator. You have to use a wrench to get it off, not sure what size it is. Once you undo the fuel line the next step is to unbolt it from the fuel rail. There will be two screws that run in the side of the fuel pressure regulator that are facing the driver side of the car and are threaded in towards the passenger side of the car, just undo those two screws and the regulator should come off. Just repeat the process backwards to put it back on.

SOURCE: Where is the fuel pressure regulator on a 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,

use the pressure test port on the top of the engine, it is on the fuel rail that supplies fuel to the injectors, looks like a tire valve, will have a plastic cap on it.

SOURCE: fuel pressure regulator had no vacuum line connected

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

If your referring to the fuel pressure regulator than pull off the vacuum hose that is attached to it. Start the engine. If gas comes out replace it. If no gas comes out its probably fine.

How to change a fuel pressure regulater do i have to pull fuel rail


You should not have to pull the fuel rail to remove the fuel pressure regulator. Just remove the vacuum lines, and the bolts. Make sure to relive fuel pressure before removing the fuel pressure regulator. To relive the fuel pressure, remove the fuel pump fuse or relay, and start the engine. This will relive the fuel pressure.

2001 Pontiac grand am looks like some type of fuel problem. The car will not run but about 5 or 10 seconds at a time. We have already changed the fuel pump, but it didn't seem to help.


If the fuel filter has not been replaced, check the fuel pressure regulator at the fuel rails and make sure the vacuum line has not been disconnected or damaged in anyway. If the vacuum line is good, check the fuel pressure regulator for any damages and malfunction. Check the fuel pressure at the shredder valve and you should have 42 to 45 psi. Good luck and hope this helps, keep me posted. Be glad to help you get your car running 100% again soon
