High Pressure Relief Valve for '05-'06 LBZ Duramax Common Rail
[1110010013]

This is the OE Bosch pressure relief valve located in the driver's side fuel rail on the 2006 - 2007 Duramax LBZ engine. This valve may open prematurely triggering the "Service Engine Light" and causing a "fuel rail PSI low" problem. Once this valve is weakened it continues to deteriorate. Replacing the valve with a new one is much safer than shimming it and taking your chances with the high pressures that this valve was designed to protect from.
