Fuel Rail Pressure Gauge - GM 2006-2010

Low fuel rail pressure readings can be a sign of fuel delivery trouble. Using 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. To ease installation, PPE also offers a 9 foot Fuel Rail Pressure Gauge harness (513010100) that is recommended but not required.
