This kit allows you to remove the Fuel Pressure Relief Valve (FPRV) located on top of the intake runner of your LB7 6.6L Duramax. This modification allows the necessary clearance needed to run larger aftermarket y-bridges or turbo inlets which would otherwise interfere with the factory hard lines running through this area of the engine valley. These parts are included standard with all WCFab LB7 y-bridge kits.
