First, disconnect the neg on the battery. Then bleed the fuel lines by disconnecting the lines that are connected to the fuel pump. The hose that connects to the tank that leads to the gas capped needs to be removed. Remove it closest to the tank. It should be on with a o-ring that you tighten. Loosen the straps and the tank will start to drop when you have the clearence to see the lines of the fuel pump, disconnect all of them. Drop the tank completely. Remove the fuel pump and replace. There may be a heat shield in the way. You can either bend it out of your way or take it off.

Yes ,the tank has to come out, its pretty obvious what has to come apart to remove it. it may be helpful to remove the drive shaft in some cases. you will need special tools to remove the lines at the tank.

Fuel pressure spec for 2005 pathfinder. I am performing a fuel pressure test and want to understand what the fuel pressure should read regulated and unregulated.

51 psi. I believe the regulator is built into the pump, so there is no unregulated number. Do you see a regulator or return line on the fuel rail?

How to change a 2005 nissan sentra fuel pressure regulator

If you want to replace the fuel pump regulator you are better off getting the whole fuel pump module I know its expensive.The problem is you went on line and there is a bunch of chatter about the fuel pump causing delayed starts. They are right. There is a TSB Nissan put out this includes the fuel pump and there is no mention of the regulator that I know of.

2005 golf mk5 1600fsi low fuel pressure replaced high pressure pump low pressure pump and pressure switch still the same does ecu need update

Check for a fuel pressure regulator. If you are testing the pressure at the end of the line, the fuel has already passed through the regulator. I'd be willing to bet the pressure coming from the pump(s) directly is up to snuff.

Low fuel pressure on neon 2003,have change fuel pump,but pressure is low can start if tank is full


Check the fuel filter and fuel pressure regulator. They are part of the same assembly and are located on top of the fuel pump. To replace the regulator # Disconnect fuel supply line at the Filter/Regulator nipple and releas locking spring tab (2 in diag.) on the regulator, then turn counterclockwise and pull out. To test regulator use a gauge like this in fuel lines:Pump Pressure Tester.
Pressure in 2003 should be 58psi (48 in 2001 engines). Pressure will drop of about ten psi when you start engine.

There is also an automatic shut down relay ASR. If problem is the ASR the pressure will go down when the relay cuts off power to pump. Read voltages and see if the problem is electrical first before going for the regulator.

Have troble starting engine after letting seat for a while with unit hot have change fuel regulator next to intake and change out body trodel position sensor

You need to check fuel pressure with a fuel pressure gauge. The regulator is a good guess but the fuel pump can also be letting fuel pressure drop. Once fuel pressure drops on a hot engine the fuel in the fuel rail will boil and essentially be a vapor lock condition. Fuel pressure should be around 56 psi and hold steady for at least 45 minute to an hour. If it drops within a couple of minutes to check valve in the pump is probably bad and the fuel pump module will need to be replaced.

The other thing, when you replaced the fuel pressure regulotar is is possible that you did not get all the old pieces from the old regulator out of the fuel rail. It is common for the screen and o-ring from the old regulator to stay in the fuel rail and they need to be removed carefully with a small pick.

Where is the fuel pump located in a 2005 Neon and how do you replace it?

Locate the Fuel Filter and Fuel Pump

  • Raise the Neon's rear end on jack stands. Remove the panel inside the trunk covering the fuel pump assembly. The fuel filter should be on top of this. On most Dodge Neons the filter is usually directly attached to the fuel pump. In that case, those two parts should not be separated and should be replaced together.Its a silver dome about 2.5 inchs round with a single plastic hose coming off it.

  • REMOVAL :-------

    1. Refer to Fuel System Pressure Release in the Fuel Delivery System section of this group. The fuel filter/fuel pressure regulator is located on the top of fuel pump module. Fuel pump module removal is not necessary.
    2. Raise vehicle on hoist.
    3. Disconnect fuel supply line at the Filter/Regulator nipple.
    4. Depress locking spring tab on side of Fuel/Regulator and rotate 90 ° counter-clockwise and pull out. NOTE:Make sure that the upper and lower O-rings are on the Filter/Regulator assembly.

    Lightly lubricate the O-rings with engine oil.

    1. Insert Filter/Regulator into the opening in the fuel pump module, align the two hold down tabs with the flange.
      1. While applying downward pressure, rotate the Filter/Regulator clockwise until the the spring tab engages the locating slot.
      2. Connect the fuel line to the Filter/Regulator.
      3. Lower vehicle from hoist.----------------

    Chevy burb 2005 fuel pressure drops in rail after vehicle sits for awhile... where is the Presurre Regulator?

    The pressure regulator is located on the left side; driver side common rail -- however, that is most likely not your problem. You either have a bad check valve in the fuel pump inside the fuel tank or you have a fuel injector staying open...and leaking fuel pressure. The regulator only works when the vehicle is running.
