6.Check for any condition that may negatively affect the Pressure Test Kit’s operation. If readings are inconsistent, or if it appears that the fuel gauge is not functioning properly,
the Test Kit should be serviced by a qualified service technician. Many accidents are caused by poorly maintained products.
7.Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one product may become hazardous when used on another product.

23.Never remove any fittings with the engine running.
24.Never loosen any fittings or attempt to remove hoses of vehicle or Pressure Test Kit until you have relieved the fuel system pressure. Refer to the vehicle manufacturer’s service manual
for specific fuel pressure relief procedures.
25.Always check all connections for leaks during the testing procedure. At any sign of leaks, turn off the engine or disable the fuel pump. Clean up any spilled fuel and repair all leaks before resuming test.
26.When preparing for pressure testing, make sure the vehicle’s transmission is placed in “PARK” or “NEUTRAL” and the emergency brake is applied.
27.When the test is complete, de-pressurize the system and remove the Pressure Test Kit. Re-assemble the vehicle’s fuel line(s) to its
original condition. Start the engine and check for leaks. If any leaks are present, stop the engine, relieve fuel pressure and repair all leaks.
