I have a 92 cabriolet. The fuel pressure regulator is a metal object plugged into the end of the fuel rail in the engine compartment, on the passengers side of the vehile. If you follow the fuel lines from the rear of the car to the front, both of the lines will attach to a cylindrical metal object. The 3rd connection of the regulator plugs into the fuel delivery rail. So one connection is fuel input. One connection is fuel delivery to the engine. One connection is fuel return to the tank. There also may be a vacuum line attached to it as well. A photo of a regulator is at http://images.wrenchead.com/smartpages/partinfo_resize/DUS/217-101.jpg
I have no interest in the photo other than as an explanatory tool.
To remove it, you would remove 2 bolts holding it in place.
remove all fuel lines and vacuum lines
pull it from the fuel rail.
CAREFUL..much fuel will spill!

Renault megane cabriolet 2001 16v IDE engine fault code P0190 Does anyone know what part needs replacing?
Fuel pressure regulator
After 1983 Volkswagen Rabbit gti sets for about 20min it is hard to start?
Check the check valve located at the inlet of the fuel pump for leaks. It sounds like the fuel accumulator has failed. get under car , remove fuel pukp and accumulator assembly. Remove fuel accumulator, drain unit. Shake unit, if it has fuel inside it has an internal leak and must be replaced. The engine heatsoak causes fuel to boil, the accumulator maintains pressure to prevent this issue.
How do you bypass a fuel accumulator on a 1988 volkswagen fox?
You don't! Vw's use a CIS fuel injection system (CIS stands for Continuous Injection System), the fuel accumulator holds the fuel pressure when the car is off, so it can start right up when you crank the engine again, since fuel is right there at the nozzle tip of the fuel injectors.
1981 VW Rabbit hard to start when hot?
Could be bad compression, with a bad head this problem gets worse with higher temperatures. Hard starting at hot could be a failing ignition coil, does the engine miss under load at hot? It could also be a failed fuel pressure accumulator or fuel check valve. Scrooch under car, find the fuel accumulator ahead of rear wheels on passenger side. Next to the fuel pump (the noisy unit humming along during operation) there is a can with 2 lines going into it. It's smaller than a soup can. If the car has high miles I would just replace the accumulator as it will probably have failed in the 28year old car. If replacing the accumulator doesn't help, replace the check valve on the fuel pump.
What would cause 1994 Chevy Cheyenne not to get fuel after replacing fuel injectors and fuel pressure regulater?
fuel filter? fuel lines? what all have you checked.
How do you discharge pressure from the fuel system before replacing the fuel filter in a 2000 Chevy Astro vans?
I remove the fuel pump fuse or relay while the engine is running. The engine will run until the pressure has dropped. Leave the fuse or relay out until you have finished replacing the fuel filter.
After replacing the fuel pump and fuel filter the engine still does not start until the fuel tank buzzing goes off. 1995 Ford Explorer?
try replacing the delta pressure feedback sensor. this fixed my explorer.Or you can try replacing the relay.
Why wont your 1994 suberban stay running?
I would suspect fuel delivery problems. Start with replacing the fuel filter. If it still has trouble have a fuel pressure test done to test the fuel pump and fuel pressure regulator.
On a 1991 Camaro RS 3.1 liter 6 cylinder can the fuel pressure regulator be replaced without replacing the fuel rail?
The fuel pressure regulator has one bolt holding it in place.l
Do you have to change fuel pressure regulator when replacing thermostat for 2002 chevy malibu?
Not unless you BROKE it.
Why isn t the car starting after replacing the fuel pump?
Check your fuel pressure. No pressure means the pump is not running or defective. Check for voltage at the pump harness and pump relay. If you have voltage and fuel pressure to spec, then you have some other issue, and the fuel pump is not the problem.
Why do you have to keep replacing your fuel pump on your 1995 Oldsmobile aurora?
Check the pressure control unit ( located on the fuel rail ). When this unit no longer gives a consistent pressure read it will "eat" electric fuel pumps.
