A specialized tool designed to assess the performance and functionality of automotive fuel injection systems. This diagnostic set typically includes a pressure gauge, adapters, and hoses necessary to connect to various points in the fuel system. Technicians utilize the kit to measure fuel pressure, check for leaks, and evaluate the overall health of fuel injectors.
The use of such equipment enables precise troubleshooting, preventing misdiagnosis and costly unnecessary repairs. It provides quantifiable data regarding fuel system operation, contributing to improved engine performance, fuel efficiency, and reduced emissions. Historically, these devices have evolved from simple mechanical gauges to sophisticated digital instruments providing detailed system analysis.
