During forced induction development with the 2.4L ECOTec there was an issue with fueling on the stock fuel rail. The stock fuel rail starts with supplying fuel to the 4th cylinder first, and then the other cylinders. This center feed fuel rail was developed to bring fuel to the center of the rail which allows the fuel pressure to remain constant throughout the entire fuel rail. Larger inner volume than the stock rail to buffer the pulsing of fuel injections. With the stock rail at it’s best at low horsepower, when you increase power with applications that are boosted, our solution is to make sure all of the fuel flows evenly reaching all of the cylinders
The fuel rail is created from a billet piece of aluminum that goes through many CNC operations. The rail is then beautifully finished to a black anodized which increases the thickness of the natural oxide layer on the surface of the meta for long term protection. The fuel supply reaches the center feed rail by a new custom stainless steel -6AN line with AN fittings on each end. To easily attach to the stock fuel line, a factory style disconnect is included and looks great!
