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.
98 Oldsmobile Silhouette 3.4 SFI smell raw fuel after tuning off engine then fails to start because it's flooded?
The Fuel pressure regulator is the most likely cause. It is the circular device most visible after you take of the plastic cover for the engine. It has a vacuum line that connects to the Throttle body or intake manifold. What happens is the diaphragm in the fuel pressure regulator is leaking and allows raw fuel to leak through the vacuum line and into the manifold or throttle body. if you replace the fuel pressure regulator it should fix the problem.
Where is the fuel injection pressure regulator located on a 03 f350?
The fuel injector pressure regulator is located in the injector fuel pump. Most pressure regulators cannot be separated from the fuel injector pump.
Where is the fuel pressure regulator located on a 96 Chevy Tahoe?
I think the fuel pump is the regulator on fuel injected engines. The FPR is located on the driver's side of the engine, it has a vacuum hose going to it and is held on with a spring clamp similar to AC connector clamp. On most 1996 Chevy Tahoes the fuel pressure regulator is actually inside the intake manifold. You must remove the intake manifold to replace it.
Why your impala idles rough but takes off fine?
Most likely cause could be the fuel pressure regulator located on injector rail with vacuum hose attached to it. This vacuum hose when disconnected after the engine has been shut off 15 minutes should show signs of fuel indicating a bad regulator.
Where is the fuel pressure regulator on the 1997 GMC Safari Van?
The fuel pressure regulator is located under the upper manifold plenum behind the injector (or spider assembly), because it is inside the manifold no vacuum line is necessary. You should note,however that none of the "popit type" injectors have fuel around them as this is the most common failure of this fuel system.
Locate fuel pressure regulator on a 1999 Chevy blazer?
It is most likely on the fuel pump
Where is the fuel pressure regulator on a 1998 Chevy S10 Blazer 4.3?
it is located on the fuel rail .
What causes too much air in fuel injectors?
Not enough fuel to them. Most l;likely a fuel pressure regulator problem
Where is the fuel pressure regulator on a 1994 Buick Lesabre?
All Fuel Pressure Regulators are usually attached to the Fuel Rail. In any case, they have a return line to the fuel tank. On your engine you may have to remove the pretty "Plastic Cover" that covers the top of the engine to see the fuel rail and the pressure regulator. Look for a "tube" that has fuel injectors going from the bottom of it and into the top of the intake manifold. The fuel pressure regulator is a round looking device attached to the end of the fuel rail with a small fuel line coming out the botttom and a vacuum line attached to the top of it. At least in most cases this is what it will look like. Especially if it an OEM set-up. Aftermarket set-ups will differ. TommyTrouble
Do electric fuel pumps have an automatic pressure?
Some do. I'm about 90% sure your car does not. The part that controls the fuel pressure is called a fuel pressure regulator. Most are located near the engine, but some import and Chrysler's have a 'returnless' system, where the regulator is built into the fuel pump module assembly, in the gas tank.
Where is the fuel pressure regulator located on a jeep grand Cherokee limited with six cylinder engine?
On the end of the fuel rail at the front of the engine. The rail holding all your injectors. It has a vacuum line running to it. Its not very big. Depends on the year, most are part of the pump module in the fuel tank.
