ABOUT THE TESTER
The Fuel Injection Pressure Tester Kit is designed to perform fuel pressure tests on most
domestic and import cars and trucks. The tester saves you time and money by helping you

and fuel economy.
The tester can help you identify and diagnose:
• Low fuel pump pressure • Leaking fuel injectors
• Faulty fuel pressure regulator • Clogged fuel filter
• Leaks in the fuel system
