The 6 Best Fuel Pressure Testers
Editor's Notes
September 26, 2019:
Large kits like the OTC 6550PRO and the Lisle 55700 are excellent options for mechanics who would otherwise end up needing to find and purchase individual adapters. Testing fuel systems often requires a very large assortment of tools because there is no unified manufacturing standard for including valves or even a standard for what sort of valve is used. If you're only concerned about testing a few fuel system configurations, smaller economical kits like the Actron CP7818 and the OEM Tools 27167 will do just fine. The OEM Tools tester includes a multimeter which will definitely come in handy if you don't already have one. Make sure you know how to use a multimeter safely, as using the wrong settings can result in damage to the tester and the car's electrical system.
Working on pressured systems or electrical systems is very dangerous to yourself and to the equipment. It should only be done by trained automotive technicians to avoid injury or property damage.
