Do not smoke, or test near open flames or some hot components 5.Perform service in a well-ventilated, outdoor location 6.Make sure all connections are tight to avoid fuel leaks. Use teflon tape if needed 7.No bleed valve and drain hose, please wrap cloth around hose connection before relieving pressure from fuel line and removing testing component

• Check Fuel Injector Pump Pressure: The pressure gauge is designed for checking the fuel injection pump pressure easily and quickly. You can compare the pressure value to the manufacturer's recommended reference range, aid to diagnose gasoline engine fuel system. Low fuel pressure can be caused by kink/leak/clog on inlet supply side components, a bad fuel pump or fuel regulator, low tank pressure. High fuel pressure may caused by a defective fuel pressure regulator or kinked outlet return line
• Necessary Fuel Oil Injection Pressure Tester Tool: Testing fuel pressure is an essential part of the troubleshooting process of fuel injection system. Proper fuel pressure is vital for engine operation and performance. Too high fuel pressure can cause the engine to run too rich, incomplete combustion, excessive fuel consumption, increased carbon buildup, exhaust exceeding the standard. And a low fuel pressure will lead to a lack of horsepower, stalling, and a slow or no-start condition
