Getting the right amount of fuel to your motor is a crucial task. Too little fuel and your engine will have fuel starvation that could potentially cause it to fail completely. Too much fuel and your vehicle will not run correctly, and possibly blow out fuel lines creating a fire hazard. Adding Pontiac Tempest fuel pressure regulators is a great way to ensure that your ride produces maximum performance and maintains reliability. Here at Andy's we have a fantastic selection of Pontiac Tempest fuel pressure regulators. With everything from top of the line racing units to more affordable options, you are sure to find the perfect Pontiac Tempest regulator for your application in our extensive lineup.

Most fuel injected vehicles come straight from the factory with a fuel pressure regulator. However, if you have tweaked your vehicle with go fast parts including high-pressure fuel pumps the stock regulator may not be up to the task. In this case you may need an adjustable Pontiac Tempest fuel pressure regulator so that you can precisely dial in the pressure you need to maintain optimal performance. Whether you are getting an OEM regulator or a performance model, fuel systems can be tricky to work on so we recommend using a competent mechanic when it comes time to install the unit.

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

Q: What is a fuel pressure regulator? Why buy a fuel pressure regulator?
A: 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.

Q: Will installing an aftermarket fuel pressure regulator add horsepower to my vehicle?
A: Not directly, but when adding an aftermarket fuel pressure regulator and high flow fuel pump to your modified engine, it can help deliver the additional fuel needed for optimum performance.
