Watch a step by step product demonstration of the DFIT from Hickok/Waekon. Diesel engine fuel injection common rail systems have been difficult to diagnose for years. Because of the very high pressures in the fuel system and the location of the pumps, regulators, and fuel injectors, accessibility to these components is difficult. To address this we have developed a new technology for testing the fuel delivery system that takes only 15 minutes to perform. Providing a complete, accurate analysis of the high-pressure pump, regulator, pressure sensor, and fuel injectors. Eliminates beaker testing, except to pinpoint which specific injector is leaking excessively.
