2004.5-2010 GM 6.6L Duramax Ported Fuel Rail Fitting

PPE’s Ported Fuel Rail Fitting replaces the restrictive stock fitting and helps maintain fuel rail pressure during heavy engine load situations.

This high-quality stainless steel fitting increases the available fuel flow volume from the CP3 pump to the fuel rail. Adequate fuel flow is vital to producing maximum efficient/clean horsepower.

These fittings benefit both fuel rails since the driver-side fuel rail feeds the passenger side.
