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.

How does the fuel regulator on a Mazda mx3 work?
By regulating the fuel pressure
What happens when the regulator dose not work on a car?
If it's a window regulator the window will not move. If it's a fuel pressure regulator the engine will run badly or not at all. If it's a voltage regulator the battery will be under or overcharged.
Will a intank fuel pump work with a carburetor?
Yes, if you have a fuel pressure regulator.
Why won't an electric fuel pump work on an 1982 Camaro?
it will work but you have to use a pressure regulator in line so you can set the fuel pressure down to 6 psi. for the carburetor
What is the function of the fuel regulator?
Every fuel injected car has a fuel pressure regulator. It's there because fuel injected cars work by opening valves (fuel injectors) for certain amounts of time to deliver a specific amount of fuel.
How do you change a fuel filter for Chevrolet HHR?
The only fuel filter on 2006 chevy hhr's are located in the fuel tank and the fuel tank only, if you are having a fuel related issue try injector cleaner first then work your way up to the fuel pressure regulator( you can probably have pressure tested at a 3rd party mechanic pretty cheaply). If pressure is low replace the regulator first then work your way to the fuel pump if problems persist.
What is the fuel pressure for a 1998 Chevy 3500 with a 454 engine?
The standard fuel pressure for a 1998 Chevy 3500 with a 454 engine is 50 PSI. If fuel pressure drops much below this level, the fuel injectors will not work properly.
When a fuel pressure regulator leaks on your 1999 Oldsmobile alero can it cause the fuel pump to work intermittently?
I doubt it. I have a 01 Alero that had to have a new fuel pump at about 100,000. If you have a leaking regulator, you need to replace it. It is a fire hazard. The symptoms for the bad fuel pump were normal function then it would just stop working. When it cooled down it would work again.
Will a 1991 Buick Century and a 1986 Buick Regal have interchangeable fuel pumps?
Do they have the same engine? If not, then no, it wont work. If they do, make sure they have the same fuel pressure requirment. If the engine and pressure is the same, they should be interchangeable.
Will a 1985 Chevy 350 work in a 1992 Chevy 350 for a replacement engine?
No it will not. Now it will bolt right in there but the transmission will not work and the fuel pump in the fuel tank has to much fuel pressure for a carburetor
What you have to change on the fuel tank as well as the lines to make a carburetor motor work in a 1993 Chevy camaro?
you would need a fuel pressure regulator to control the flow to the carb to keep the pressure about 5 or 6 PSI, you shouldn'rt have to do anything with the pump in the tank.
Why would an engine die while turning a corner and restart but not stay running?
A weak or bad fuel pump. When youu turn a corner you cause the fuel in the fuel tank to move abruptly from one side of the tank to the other. The rushing movement of the fuel causes the pump inside the tank to work harder causing a week pump to shut down.Answer:Another possibility is the fuel pressure regulator.
