Due to the variation in fuel injector designs, we optimized the alignment of the fuel injector inlet to the fuel plenum, regardless of which fuel injectors you may choose to purchase.Not only is the fuel plenum aligned vertically to meet the fuel inlet, but the plenum was optimized horizontally to ensure that the fuel inlet has as much chance of getting fuel as possible, with out affecting delivery to the next fuel injectors down the plenum. We found the stock rail prevented quite a bit of fuel to get to the end of the fuel rail. We found the Border rail had no fuel injector penetration into the fuel plenum. Due to the variance in fuel injector body diameters, each rail is designed for the optimal fuel injector pentration. (ie, no fuel rail is the same, internally or externally.) I hope our attention to detail is clear and understandable.
