Pacific Performance Ported Fuel Rail Fitting for GM 6.6L Duramax (2004.5-2010)
Reduces fuel pressure drops caused by restricted stock fuel rail fitting
One or two fittings can be used simultaneously in left and right fuel rail
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.
