Rated 5 out of 5 by Professional Quality The Actron CP7838 is a top notch fuel pressure tester. However, it's best to call ahead to check availability, as they are not available at all locations and the Pep Boys inventory system's ability to check inventory at other stores is not what one would desire. I was told the this item would have to be special ordered because it was not in any of their stores. But after calling the North Miami store, they had it in stock and held it for pickup.

Rated 3 out of 5 by Room for improvement I blew my valve cover gasket after a Weber Carb conversion and discovered fuel was dumping into my engine. There was not a fuel pressure gauge available in store that fit my Weber fuel pressure regulator so I purchased this inline gauge. At first I was not getting a reading, but after a bit of messing around I was able to get a reading of 4 psi. Dialed it back to a reading of nothing (which is obviously an inaccurate) and my problem was solved. Be aware that in the lower psi range one will not provide a precise reading due to the absence of markings and a large blunt tip needle. What would be nice would be if Actron or Pep Boys provided the option of purchasing a different Fuel Pressure Tester without such a large range that would provide a more precise readings.
