On a standard fuel injected 4.3l V-6 the regulator is located under the intake plentum next to the central fuel injector. If you have never had one of these engines apart it can be a little tricky, use caution when setting the plentum back on.

Where is the fuel pressure regulator located on a 1988 Dodge B-150 van, 5.2 liter? I've been told it's on the fuel rail. Where is the fuel rail?


If you have throttle-body fuel injection, you don't have a fuel rail. The fuel pressure regulator should be mounted to throttle body.

Where is location of fuel volume regulator


Fuel pressure regulator ! An it's location is inside the fuel tank .
The fuel pump (FP) module contains the fuel pump, fuel pressure regulator and the fuel sender assembly. The fuel pressure regulator is attached to the fuel pump in the fuel pump module located in the fuel tank. It regulates fuel pressure supplied to the fuel injectors. The fuel pressure regulator is a diaphragm-operated relief valve. Fuel pressure is established by a spring preload applied to the diaphragm. Excess fuel is bypassed through the regulator and returned to the fuel tank.

I need to replace de fuel presurre sensor in a pontiac montana ,do i have to just replace the sensor ,o the sensor came with the fuel pump?thank you


Replacing the fuel pressure regulator, involves just replacing the regulator at the end of the fuel rail in the engine compartment, but fuel pressure sensor - does this mini-van have a fuel pressure sensor?
replacing the fuel pressure regulator: (1) locate it at the end of the fuel rail in the engine compartment,
(2) relieve fuel system pressure (3) disconnect fuel pressure regulator vacuum line. (4) remove fuel pressure regulator retaining screw (retain for re-use (5) using a shop towel to catch spilled fuel, lift & twist Fuel pressure regulator to remove it from the fuel rail. (6) remove/discard retainer and spacer bracket from the fuel rail. (7) remove fuel pressure regulator from the engine fuel return pipe. (8) remove/discard Fuel Pressure Regulator inlet O-ring (9) Check Fuel Pressure Regulator filter screen for contamination - if contaminated, replace Fuel Pressure Regulator. (10) Lubricate new Fuel Pressure Regulator inlet O-ring with clean engine oil & install onto the Fuel Pressure Regulator inlet. (11) Install the fuel return pipe onto the Fuel Pressure regulator (12) Install new retainer & spacer bracket into the slot on the fuel rail.
(13) Install Fuel Pressure Regulator onto Fuel Rail & tighten Engine Fuel Return Pipe nut to 13 ft-lbs (17 Nm). (14) connect Fuel Pressure Regulator vacuum line, (15) Install Fuel Pressure Regulator attachng screw & tighten to 76 in-lbs (8.5 Nm). (16) Inspect & verify that retainer & spacer bracket is engaged in the slots on the fuel rail. Grasp & pull on the Fuel Pressure Regulator.
to ensure that the Fuel Pressure Regulator is properly seated. (17) inspect for fuel leaks with this
procedure: On 2sec,(holy rollers), off 10sec will be left on, inspect for leaks while running.

I need to know where the fuel pressure sensor is located on the 2000 chevy express van.


There is not really a fuel pressure sensor. There is a fuel pressure regulator. The fuel pump pumps up pressure and the pressure regulator allows the fuel to return to the fuel tank if the pressure reaches 37psi in the 4.6 liter. It is located on the intake manifold. It is round about 3 inches in diameter, and has a fuel line on both sides of it.

Where is the location of the fuel regulator valve


If you mean your fuel pressure regulator. It's located on the CSEFI injector assembly, the regulator is located under the air intake plenum on the back of the fuel meter body.
If the regulator is bad it may cause either a drop in fuel pressure or an increase in fuel pressure at the rail . A drop in fuel pressure, if severe enough, can cause bad or no idle condition, engine starving for fuel and etc.

If the regulator is causing excessive pressure it can cause fouled plugs, black smoke from exhaust and rough engine performance.
Before you change the regulator check for cracked, rotted or disconnected vacuum hose.

Also you can connect a fuel pressure gauge to the schrader valve on the rail and monitor the pressure to see if it is in specifications, or to see if the fuel pressure drops rapidly after engine shutdown.

Hope this helps and good luck with your project. Thank you for using Fixya

Where is the fuel regulator located on a 1988 tbi


Sits inside the throttle body, you would have to open to install regulator. Also check your fuel filter make sure it's not clog, fuel filter is under truck on fram rail, while your there do a fuel pressure test, with a fuel pressure tester, should have 13psi.
