What is a fuel pressure regulator? Why buy a fuel pressure regulator?
The fuel pressure regulator regulates the fuel pressure that goes into the engine. The car's computer does not control the fuel pressure regulator; it is controlled by the engines vacuum. Depending whether the idle is high or low the fuel pressure regulator opens and closes giving more or less fuel. With a high performance motor, an adjustable fuel pressure regulator is needed to increase the amount of fuel given to the engine since larger injectors and fuel pump will be utilized.

How do you install a fuel pressure regulator?
You disconnect a vacuum hose and one fuel line on your fuel pressure regulator and replace it with the new adjustable unit within minutes.
