Safely test car and truck fuel pressure systems equipped with a Schrader or fuel access valve test port on the fuel line. 

The Fuel Pressure Tester Kit works on most domestic fuel injected vehicles having a Schrader valve test port on the fuel rail. This includes Ford high pressure central fuel injection and GM, Ford, and Chrysler multi-port fuel injection. Multi-port means one fuel injector per cylinder.

Tests:

• Fuel pump check valve i.e. leak down test
• Fuel pressure regulator
• Weak fuel pump
• Fuel line integrity i.e. clogged or damaged fuel filter 
• Leaking injector(s).

*Do not use the Fuel Pressure Tester Kit with Diesel or Flex Fuels.
