This fuel injection part reduces fuel pressure drops that are caused by the restriction of the stock fuel rail fitting. EVIL ENERGY fuel rail fitting replace the restrictive stock fitting and helps maintain fuel rail pressure during heavy engine load situations.
The duramax fuel rail fitting is constructed of stainless steel which is anti-oxidation, anti-corrosion and anti-rust. High quality 304 stainless steel increases available fuel flow volume from the pump to the fuel rail. Adequate fuel flow is vital to producing maximum efficient / clean horsepower.
The fuel rail fittings benefit both fuel rails, since the driver side fuel rail feeds the passenger side. One or two fittings can be used simultaneously in left and right fuel rail. Easy to install. Recommended to use some petroleum jelly to lubricate the fitting during installation.
Weld-free construction that gives fuel rail fitting better leakproofness. Threads in perfectly and doesn't leak.
