Tubing is available in bulk form, cut to length, or various stages of machining and assembly. Rails that we assemble are vacuum nickel brazed or silver brazed then pressure tested for leaks. Stainless rails are mounted using brazed-on straps, or our billet aluminum 2-piece mounting stanchions, available in various lengths for installation of EFI injectors with different overall body lengths. (See EFI INJECTORS on Page #139 for length d etails). We can supply a complete rail for our manifolds or yours. We can machine a rail to your print, or supply a partially machined rail so you can finish it. Individual components available ! © 2024 PRESSURE DAMPENING COMPONENTS The opening and closing of EFI injectors causes fuel pressure fluctuations, affecting the fuel delivery to individual cylinders. Dampening the pressure pulses in the fuel rail can improve the fuel distribution. Group-Fire systems fire more than one injector at a time cause the highest pressure pulsing due to a large instantaneous demand for fuel. Sequentially timed systems, opening one injector at a time, creates a smaller instantaneous demand, thus lower pressure fluctuations.
