Low fuel rail pressure readings can be a sign of fuel delivery trouble, and thanks to the PPE Fuel Rail Pressure Gauge it can be headed off before real trouble arises. This gauge lets you know when your diesel is starving for fuel or when it is running at its optimal tune. PPE also offers a 9 foot Fuel Rail Pressure Gauge harness (513010100) that is recommended to ease installation, but is not required.
