A fuel pressure regulator is an item that plays a key role in any fuel system, but doesn’t always get the level of care it deserves. One thing that performance or racing enthusiasts might not pay enough attention to is the location of where they mount their regulator. A mistake in where you mount a fuel pressure regulator could lead to issues keeping the car fed with the correct amounts of fuel, especially at the track. Fuelab’s John Light does a masterful job hitting on some important details in this article on location of a fuel pressure regulator.

Best-Fuel-Pressure-Regulator-Location-300x225The basic purpose of a fuel pressure regulator is to ensure there’s enough pressure built up to support the system, whether that ends with a carburetor or fuel injection. The regulator keeps the fueling constant and consistent no matter what the fuel demand is, when there’s a change. Without a properly matched regulator, any fuel system will experience serious lean or rich conditions that could lead to engine failure.

Different combinations and applications will have different needs where a fuel pressure regulator should be placed. Not placing the regulator close enough to the final destination of the fuel can cause a dramatic pressure loss. In the How-To article, Light examines the different locations that many with performance cars look to mount their fuel pressure regulators, and where issues can arise for each. This is critical for the extreme conditions that occur in drag racing during the various stages of a pass.
