MOTAFAR Compression Automotive Cylinder Powerstroke Review

The pressure gauge tester can test fuel or low side oil pressure. It comes with all the fittings needed for both 6.0 & 7.3 engines. The tool is primarily designed to test fuel pressure while driving. After any fuel pressure test, you have the option to leave the adapter installed, and cap it with one of the provided jic caps. The jic plug is for to plug off the end of the tool for storage. This is a must, to accurately see the pressure drop with a load on the engine. This tool can also potentially work on many other engines, including gas engines. If the engine has a 7/16-20 thread test port at the fuel rail, just remove the shrader valve before connecting the tool.
