Where do you hook up a fuel pressure tester?

Find a Schrader valve fitting on the fuel rail. Most vehicles will have them, although it may be hidden under a fuel rail cover or other plastic engine cover. Remove the Schrader valve cap. Attach the appropriate fuel pressure tester fitting.

What is a good fuel pressure reading?

Fuel pressure for most vehicles should stay in a 5- to 10-psi range.

Does fuel pressure drop at idle?

Idling you’ll be at approximately 15 ~ 20 inches of vacuum which means fuel pressure must drop by 15 ~ 20 PSI to maintain the correct pressure drop across your injectors.

How do you adjust fuel pressure?

When adjusting the fuel pressure, the engine should be at its lowest setting. A screw is held in a fixed position with an Allen wrench while a nut is loosened on a regulator. The fuel pressure can be raised with the help of a screw clock. The way to lower pressure is to turn the screw count clockwise.

How long does it take for fuel pressure to drop?

Usually a bad fuel pump or leaking lines will drop to 0 in a matter of seconds. Leaking fuel injector(s) will drop closer to 0 a little slower.
