Where is the Fuel Pressure Regulator in an 01 Ford Taurus?
The regulator IS in the fuel rail if you have a V-6 engine.(the 12 cyl. Tablesaurus proved too much for the street--LOL! ) Round cylinder on the fuelrail on top the engine with a 90 degree vacuum hose connector going to it. NEVER seen anything but through this shop.
Where is the fuel pressure regulator located on 2000 dodge 1500 ram van with 3.9 v6 engine?
My first question would be "why do you suspect the fuel pressure regulator bad", that being said the regulator is located on the fuel rail and has a vacuum line attached. At high RPM's the fuel pressure is higher than at idle. If you are concerned with fuel pressure, most likely there is a problem with your fuel pump or fuel filter. Best of luck
Fuel pressure regulator- dodge dakota - where is it?
here is what alldata say's you have to replace the hole fuel pump there is no seperate replaceable regulator A combination fuel filter and fuel pressure regulator is used on all engines. It is located on the top of the fuel pump module. A separate frame mounted fuel filter is not used with any engine. Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for extended service. They do not require normal scheduled maintenance. Filters should only be replaced if a diagnostic procedure indicates to do so. Fuel Pressure Regulator Operation: The pressure regulator is a mechanical device that is not controlled by engine vacuum or the powertrain control module (PCM). The regulator is calibrated to maintain fuel system operating pressure of approximately 339 kPa ±34 kPa (49.2 psi ±5 psi) at the fuel injectors. It contains a diaphragm, calibrated springs and a fuel return valve. The internal fuel filter is also part of the assembly. Fuel is supplied to the filter/regulator by the electric fuel pump through an opening tube at the bottom of filter/regulator. The regulator acts as a check valve to maintain some fuel pressure when the engine is not operating. This will help to start the engine. A second check valve is located at the outlet end of the electric fuel pump. Refer to Fuel Pump-Description and Operation for more information. Also refer to the Fuel Pressure Leak Down Test and the Fuel Pump Pressure Tests. If fuel pressure at the pressure regulator exceeds approximately 49.2 psi , an internal diaphragm opens and excess fuel pressure is routed back into the tank through the bottom of pressure regulator.
Should fuel shoot out the top of a fuel pressure regulator?
the regulator is faulty if there is fuel coming through the vacuum line. fuel should NEVER make it to the vacuum side of the regulator for any reason. the vacuum line is supposed to suck air to move a rubber diaphragm inside the regulator, allowing a valve to open and send excess fuel back to the fuel tank. if there is fuel going through the vacuum line that would explain why you are having trouble starting the car. the vacuum comes from suction inside the intake manifold, so all of that fuel is being sucked back into your intake causing the car to run extremely rich. I'm assuming that when your car finally does start you have a noticeable amount of black smoke that spews from the exhaust. you need to replace your regulator asap. the longer you wait to replace it the more fuel you are throwing down the drain, and the sooner your car will require major repairs. eventually you will wind up with fuel running past your pistons and getting into the oil, which destroys bearings. you will also wind up with fuel fouled plugs, requiring early replacement. also, the unburnt fuel can wreak havoc on your o2 sensors, clogging them with soot and requiring early replacement.
I took off my fuel pressure regulator and i can not blow through any of the holes. does that mean it is bad?
It should be closed until its relief pressure is felt, it's how it regulates. Try installing it, and crank the car with the return line from the regulator removed to check for flow. A small part like a regulator should just be replaced to eliminate it. it's not worth the time playing with it. Check your supply and return lines for blockages or air entry from loose clamps or connections that can cause engine to run rough. Hope you sort it!
