Diesel fuel systems require precise fuel sprays for reliable, consistent combustion — that’s where injector systems come in. These high-pressure systems send regular fuel streams to the engine to keep your vehicle running. The hydraulic electronic unit injector (HEUI) system is a computer-controlled system with a combined high-pressure pump and injector for each engine cylinder. It replaced traditional mechanical injection using …
