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.
- 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
