PPE Power Race Fuel Valve GM 2001-04 LB7 - 113072800
California Air Resources Board Executive Order No. D-701-25
The PPE Race Fuel Valve, made from stainless steel, replaces stock or a
shimmed pressure relief valve. This valve helps maintain fuel rail pressure
during high engine load conditions. It eliminates potential low fuel rail
pressure DTC codes P1093 or P0087 (low fuel rail pressure during power
enrichment) that are caused by insufficient pressure relief valve (PRV)
spring pressure. This leads to the valve opening too early which causes
excessive amounts of fuel to be returned to the tank.
