 Actron CP7838 Professional Fuel Pressure Tester

The added length of this hose let me drive the vehicle and watch the gauge at the same time. The gauge itself could be a little better quality but it gets the job done with ease. 

This gauge helped me check whether a hesitation problem was caused by a fuel pressure problem. The gauge is well constructed and easy to use. It attaches right into my GM 3800 fuel pressure test port without having to use any of the many adapters they include in the kit. The manual was pretty good. It would be helpful if they would print a list of common engines and what an acceptable range is for their key-on-engine-off and running fuel pressures. But you can find that information elsewhere, as the manual indicates. If you are a shade-tree mechanic or even more serious, this will work well for you.
