## Long description

Rockforce RF-904G4 fuel and vacuum pressure tester kit is a workshop tool for measuring fuel line pressure and diagnosing vacuum leaks in automotive systems. The kit includes a pressure gauge and a set of nine threaded adapters that allow connection to a variety of fuel and intake fittings. It is designed for mechanics and technicians who need to verify fuel pump output, check fuel rail pressure, locate vacuum leaks and confirm proper operation of pressure-related components during maintenance and troubleshooting.
Advantages
The kit provides broad vehicle compatibility through nine threaded adapters, reducing the need for additional fittings. The integrated pressure gauge allows direct reading of fuel and vacuum values, enabling quick verification of system conditions. The tool is compact and organized for workshop use, simplifying setup and repeated measurements without extensive disassembly of fuel system components.
Suitable for
 Measuring fuel rail and fuel line pressure on gasoline and diesel vehicles
 Diagnosing vacuum leaks in intake manifolds and vacuum hoses
 Testing fuel pump output and pressure regulator function
 Routine maintenance checks and troubleshooting in professional and home workshops
Key specifications
 Function: fuel pressure measurement and vacuum testing
 Adapter set: nine threaded adapters for multiple fitting types
 Gauge type: mechanical pressure gauge with visible scale for fuel and vacuum readings
 Connection: threaded fittings compatible with common automotive fuel and vacuum ports
 Application: suitable for use on a wide range of passenger cars and light commercial vehicles
How to use
Shut off the engine and relieve system pressure following the vehicle manufacturer's safety procedure before connecting the tester. Select the adapter that matches the vehicle fitting and attach it to the tester hose, then connect the assembly to the fuel line or vacuum port to be tested. Start the engine or operate the fuel pump as required to obtain a live pressure reading from the gauge, or use engine vacuum to read negative pressure. Interpret the measurement by comparing the gauge reading to the vehicle manufacturer’s specifications to identify low or high fuel pressure or vacuum leaks.
Usage recommendations
Always follow safety precautions when working with fuel systems: work in a well-ventilated area, avoid open flames and sparks, wear appropriate protective equipment, and follow vehicle-specific procedures for pressure relief and disconnection. After testing, ensure all connections are properly reinstalled and check for leaks before returning the vehicle to service.
