PPE Race Fuel Valve (LB7)
2001-2004 Chevy/GMC 2500/3500 HD Duramax
*50 State Legal CARB EO# D-701-25*
The PPE Race Fuel Valve is heat treated stainless steel that replaces stock or a shimmed pressure relief valve. This valve helps maintain fuel rail pressure during high engine load conditions it eliminates DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient pressure relief valve spring pressure opening, returning fuel to the fuel tank.
When upgrading to a new/bigger fuel system on my Lb7 i wanted to ensure i had no weak points, stock fprv was a easy yet cheap part to upgrade with a PPE race fuel valve.
