Does a 2002 Nissan altima have a return fuel line and a fuel pressure regulator?

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)

What causes to much fuel pressure in a Chevy caviler?
Restricted fuel return line or a faulty fuel pressure regulator.
If you are getting gas to the fuel injection but not out of the return line what could be the problem?
Fuel pressure regulator.
Where is the fuel pressure regulator on a 1990 ford bronco?
On the fuel rail. The tank return line connects to it.
Where is the fuel regulator for a 2000 Toyota corolla?
The fuel pressure regulator is located right on on the fuel rail, it has a vacuum line at one end and a fuel return line.
Where is the fuel pressure regulator located on a 2000-2001 Nissan Maxima?
The fuel pressure regulator is located at the end of the fuel rail, near the top of the engine, next to the throttle body and right below where you see the two throttle cables. The regulator is held in place by two screws. It has two hoses connected to it - a vacuum hose on top, and a fuel return hose on the bottom. To remove it, you will need to first relieve the fuel pressure, then remove the air intake duct and resonator from the throttle body and air flow assembly.
When was The Return of the Regulator created?
The Return of the Regulator was created on 2001-12-11.
How do you test a fuel pressure regulator on a 1996 4.3 Chevy s 10?
With fuel pressure gauge attached and engine running, briefly and I mean briefly, pinch off the return fuel line while watching the gauge. If the fuel pressure spikes the regulator is working. The normal pressure of the fuel system before you pinch off the return line would be 60 to 66 psi.
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.
How do you test the fuel pressure regulator on a 1989 Ford Econoline E350?
The quickest way i have found to check it is to hook up a pressure guage to the fuel rail and start the engine. During idle let pressure stabilize. Then breifly crimp or clamp off with pliers, the return fuel hose after the regulator. This is to confirm that the pump has excess pressure. Remember this is very briefly. If the pressure goes up then you are reading regulator pressure. If it doesnt go up then the pump pressure is less than the regulator pressure and may need to be replaced. Remember don't crimp the return line for more than a second or you run the risk of poping the rubber hose on the pump in the tank. It only takes a second to see if the pressure guage jumps up.
What could cause high fuel pressure on your 1991 z28 camaro?
A bad fuel pressure regulator or a clog in the fuel return line that leads back to the tank will cause this.
Where is the return fuel line on a 93 Saturn SL2?
the fuel return line is on your fuel rail. it is part of the Pressure regulator assembly. Please view my Bio for access to my Saturn help site. in the fuel folder, go to Fuel pressure lines. the return line is highlited in green for you
How does a car engine fuel pressure regulator work?
The fuel pump pressurizes fuel to a greater pressure than is needed at the injectors. There are different types of regulator, some "bleed off" excess pressure by allowing fuel to dump back into the tank via a separate return line, other regulators close a valve once a specific pressure is reached.
