Best Upgrades For Lly Duramax - April 2024

PPE Race Fuel Valve for 2004.5-2010 Duramax LLY/LBZ/LMM 113073000 with PPE Viton O-Ring Upgrade for PPE Race Fuel Valve

The PPE Race Fuel Valve (heat treated stainless steel construction) replaces stock or a shimmed pressure relief valve. This valve helps maintain fuel rail pressure during high engine load conditions by completely blocking the pressure relief port (effectively eliminating fuel return to the fuel tank). It eliminates potential low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient PRV spring pressure.
