It depends on the vehicle. On some it is located on the fuel rail, near the injectors. On others it is part of the fuel pump, in the tank.

How do you check the injector pressure regulator on a 2000 silverado 5.3 liter?
If you look at it you will see a vacuum line hooked to it, while the engine is running unplug it and the engine sound should change. If it don't then the regulator is bad. You can also hook up a fuel pressure gauge to the fuel line and read what the pressure is while engine is idleing and then unplug the regulator and the fuel pressure should go up a few LBS. If not replace regulator.
Where does the vacuum line go from the fuel pressure regulator on a 2000 Chevy 4.3 vortex?
It doesn't have a vacuum line attached to the fuel pressure regulator.
1989 dodge ram 250 fuel pressure regulator?
The van wont start and we were told it was the air and fuel regulator or is it the fuel pressure regulator that the lines to the gas peddle go into to make the vehicle run
How does the fuel regulator go on?
The fuel pressure regulator does not have an on or off position. It has a spring loaded valve that keeps a certain amout of pressure inside the fuel rail. There is also a vacuum line attached to it (from intake mainifold) which varies the tension of the spring via a rubber diaphragm to allow more fuel pressure under higher engine speeds.
What can go wrong with a fuel pressure regulator on a 98 Chevy S-10?
A fuel pressure regulator on a 4.3L can leak undetected but cause the vehicle to fail emissions.
What is a fuel press regulator?
This answer relates to an automobile fuel pressure regulator. The most common form of fuel pressure regulator is an inline chamber where the fuel enters before entering the engine. There is a diaphragm that is spring loaded on the side with the spring tension "pointing" at the fuel inlet. Normally, the pressure is preset to a desired pressure reading. Since the fuel pressure created by the fuel pump is higher than the desired pressure, the regulator keeps the pressure to the injectors at a steady desired pressure. Many fuel systems use a vacuum source to the diaphragm also to allow the pressure to go up when the vacuum drops away, such as on hard acceleration. Another feature of most fuel pressure regulators is a return port. This allows fuel in excess of the desired fuel pressure to return to the tank.
What is a fuel or a gas regulator for the Pontiac Grand Am?
The fuel pressure regulator controls fuel pressure at the fuel injectors. It uses vacuum pressure to control the pressure. It is positioned on the end of the fuel rail. If they leak, fuel will go into vacuum line causing hesitation on start-up and the smell of gas at exhaust. Warning, Fuel is under pressure. Disconnect battery and release pressure before replacement.
Why would my Chevrolet Camaro v6 2001 shake and try to go dead?
pull the vacume line off the fuel pressure regulator on the driver side fuel rail and start the car. if you have gas coming from the regulator it is flooding the engine and is your mane problem.
Where is the fuel pressure regulator on a 1999 mercury cougar?
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.
Where is a fuel pressure regulator on a 5.7 vortex engine?
Vortex engine? Got me. I thought Vortex was just a brand of supercharger. I believe you mean Vortec engine.. GM also called this the L31 (they use 3 letter/number codes for everything) This system used a SCPI (Sequential Central Port Injection) system... and the fuel pressure regulator is on the central unit, which is INSIDE the intake manifold- you have to remove the upper intake manifold to get at it (plastic part), and the Fuel pressure regulator will be on one side of the central unit where all the fuel lines go to, it has a tube on it open to the intake manifold (to read intake vacuum)
What does fuel pressure regulator do?
When your engine takes in gas, it only takes in a certain amount depending how hard the engine is being pushed, the fuel pump constantly pushes the same amount of fuel so something is needed to regulate how much fuel is going to go into the engine, the unused fuel goes through the return line back to the fuel tank.
Why is the engine RPM in idle some time go down to near 300 up to near 1300 frequently in 1998 deville?
Could be a vacuum leak or fuel pressure regulator.
