Fuel Rail Plug for Dodge 6.7 and Duramax 6.6 diesel engines. Eliminates unwanted pressure relief of fuel rail when running a high performance tuning device.

Tech Notes

This kit will replace your fuel release valve without having to shim it with washers. H&S Performance programming raises the fuel rail pressure and may cause the fuel rail release valve to open, causing trouble codes P0087 and P1011. The FRP will eliminate the valve, allowing ample pressure to the rail and injectors, all without worry of losing rail pressure or trouble codes.
