Material requirements were a problem for the manufacturer of the fuel rail, part of the electronic hydraulic unit injector (HEUI). Aluminum couldn’t withstand the operating pressure of 6,000 psi. Iron sand castings had porosity and inconsistency. Other quality requirements included dimensional control and bend & bow tolerances. Steel had a lengthy extrusion process and a lot of time was requir
