A fuel rail pressure sensor is essential because a proper ratio of fuel and air is critical for maximizing both performance and fuel economy from your Powerstroke diesel truck. Too little or too much fuel, and the engine in your F-250 or F-350 will run poorly – even possibly belching raw fuel out the exhaust if it’s too rich. A faulty fuel rail pressure sensor can give the engine computer a bad reading, likely causing drivability problems.

The Powerstroke 6.4L Fuel Rail Pressure Sensor from Alliant Power is a direct replacement for the Super Duty factory unit and is a simple way to ensure that your fuel system is up to the task of powering your rig.
