H&S 2011-2016 GM 6.6L Dual High Pressure Fuel Kit
H&S Motorsports is pleased to introduce the Dual High Pressure Fuel Kit for the 2011-2014 6.6L GM Duramax. This kit has been in development since June 2012 and is finally available to the public after over 11 months of testing and refinement. The diesel industry has been longing for this modification ever since the release of the LML/LGH platform and now the wait is over.
XDP RACE FUEL VALVE XD125
The XDP Race Fuel Valve XD125 prevents fuel from being returned to the tank when the pressure release valve is opened due to fuel rail pressure increases.
PPE RELEASE VALVE SHIM KIT 113072000
More fuel pressure equals more power and with the PPE Release Valve Shim Kit, you get both. The Release Valve Shim Kit increases the pressure needed to "pop off" the
pressure relief valve (PRV). This means that the available fuel rail pressure remains high during full throttle driving and reduces the fuel flow through the fuel return system.
The PPE Release Valve Shim Kit eliminates low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) and is recommended for high
performance and/or race applications.
